APPLICATIONS • V+ The output swings within 5mV of GND and 250mV to V+ with a standard back-terminated video load (150Ω). An internal level shift circuit prevents the output from saturating with 0V input, thus preventing sync-pulse clipping in common video circuits. Therefore, the OPA362 is ideally suited for dc-coupling to the video load. The OPA362 has been optimized for space-sensitive applications by integrating internal gain setting resistors (G = 5.2V/V) and a two-pole video-DAC reconstruction filter. The OPA362 is available in the tiny 2mm × 2.1mm SC70-6 package. 10mV RELATED LOW-VOLTAGE VIDEO AMPS Two-Pole Filter +In Out 872W RSET 3750W Enable The OPA362 high-speed amplifier is optimized for 3V portable video applications. It is specifically designed to be compatible with the video encoders embedded in Texas Instruments’ OMAP3430 and DaVinci processors or other application processors with 0.5VPP video output. The input common-mode range includes GND, which allows a video-DAC (digital-to-analog converter) to be dc-coupled to the OPA362. The TV-detection feature simplifies the end-user interface significantly by facilitating the automatic start/stop of video transmission. In shutdown mode, quiescent current is reduced to less than 1.5μA, dramatically reducing power consumption and prolonging battery life.

The following features have been integrated to provide excellent video performance: • Internal gain setting resistors (G = 5.2V/V) reduce the number of external components needed in the video circuit. • Integration of the 872Ω video encoder load resistor and 3750Ω RSET resistor used by the OMAP343x helps minimize the number of external components and also ensures excellent ratio and temperature tracking. This feature helps to keep the overall gain accurate and stable over temperature. • TV-detection support in connection with an OMAP343x multimedia processor. This feature helps to automate start/stop operation of the TV-out function and minimizes power • • • consumption. A two-pole filter is incorporated for DAC signal reconstruction. The OPA362 employs an internal level shift circuit that avoids sync pulse clipping and allows dc-coupled output. A shutdown feature reduces quiescent current to less than 1.5μA—crucial for portable applications. Although the OPA362 is optimized for the OMAP343x processor, it is also well-suited to interface with any digital media processor that outputs a video signal on the order of 0.4VPP to 0.5VPP. Figure 18 shows a typical application drawing with the OMAP343x processor and the TWL92230 Energy Management Chip.

SBOS480 – SEPTEMBER 2009 Operating Voltage Enable pin enables the op amp. The logic levels are compatible with 1.8V CMOS logic levels. A valid logic high is defined as greater than 1.3V above GND. A valid logic low is defined as less than 0.5V above GND. If the Enable pin is not connected, internal pull-up circuitry enables the amplifier. The OPA362 is fully specified from 2.5V to 3.3V over a temperature range of –40°C to +125°C. Parameters that vary significantly with operating voltages or temperature are shown in the Typical Characteristics. Power-supply pins should be bypassed with 100nF ceramic capacitors. When disabling the OPA362, internal circuitry also disconnects the internal gain setting feedback. This feature supports the TV-detection function; see the TV-Detect Function section for more detailed information. Input Voltage The input common-mode range of the OPA362 series extends from GND to 0.55V on a 3.3V supply. The input range is limited by the internal gain in conjunction with the maximum output swing capability and the power-supply voltage. Internal Two-Pole Filter The OPA362 filter is a Sallen-Key topology with an 8.5MHz cutoff frequency. Figure 19 shows a detailed drawing of the filter components. This filter allows video signals to pass without any visible distortion, as shown in Figure 20 through Figure 23. The video encoder embedded in the OMAP343x processor typically samples at 54MHz. At this frequency, the attenuation is typically 23dB, which effectively attenuates the sampling aliases. Input Overvoltage Protection All OPA362 pins are static-protected with internal ESD protection diodes connected to the supplies. These diodes provide input overdrive protection if the current is externally limited to 10mA. Enable/Shutdown The internal 872Ω resistor on the input to GND converts the output current of the OMAP3430 internal video DAC into a voltage. It is also part of the Sallen-Key filter. Using an external resistor to adjust the input voltage range also changes the filter characteristics. The OPA362 has a shutdown feature that disables the output and reduces the quiescent current to less than 1.5μA. This feature is especially useful for portable video applications, where the device is infrequently connected to a television (TV) or other video device. The Enable logic input voltage is referenced to the OPA362 GND pin. A logic level high applied to the 3.6pF OPA362 1838W ( Television 2.5kW ) VO 872W 75W 12.5pF 75W 4.22kW 1kW Figure 19.

D: 2.02V @: 30.0mV The multiburst test patterns have different sine-wave burst sections with the following frequencies: 0.5MHz, 1MHz, 2MHz, 4MHz, 4.8MHz and 5.8MHz with 420mVPP. There is no visible attenuation even at the highest frequencies, which indicates a very flat frequency response of the OPA362. As shown in Figure 22 and Figure 23, the top line illustrates the full signal and the bottom line is a more detailed view of the last three sine wave bursts. Figure 20. 100/75 Color Bar Signal at OPA362 Output The CCIR330/5 test pattern requires one of the greatest dynamic ranges, and therefore tests the OPA362 output voltage swing capability.

SBOS480 – SEPTEMBER 2009 Internal Level Shift Many common video DACs embedded in digital media processors, such as the OMAP343x processors from Texas Instruments, operate on a single supply (no negative supply). Typically, the lowest point of the sync pulse output by these video DACs is close to 0V. With a 0V input, the output of a common single-supply op amp saturates at a voltage greater than 0V. This effect would clip the sync pulse, and therefore degrade the video signal integrity. The OPA362 employs an internal level shift circuit to avoid clipping. The input signal is typically shifted by approximately 11mV. This shift is well within the linear output voltage range of the OPA362 with a standard 150Ω video load. vertical sync pulse. For the detection, a simple pull-up resistor to the processor logic supply is used on the output of the OPA362. The voltage level is pulled low if the TV (or other video equipment) is connected, or high if nothing is connected. A GPIO in the processor can be used to read this logic level and decide if a video load is connected. Figure 25 shows a scope plot with the TV disconnected and Figure 26 shows a scope plot with the TV connected; the upper line in both figures is the disable pulse. See Figure 27 for a circuit drawing that shows how to use the TV-detect signal to disable or enable the OPA362. OPA362 Disable Pulse D: 1.84V @: 1.84V Output Swing Capability Figure 24 shows the true output swing capability of the OPA362 by taking the tip of the input sync pulse to a slightly negative voltage. Even when the output sync tip is at 3mV, the output after the 75Ω series termination continues to show no clipping of the sync pulse.

Using TV-Detect Signal to Disable/Enable the OPA362 Disabling the OPA362 also disconnects the internal feedback resistor path to GND, and therefore there is no current flowing from the logic supply through the pull-up resistor to GND if no video load is connected; this architecture helps to conserve battery life. The typical leakage when the output is pulled high and OPA362 is disabled is approximately 300pA. The following functionality can be achieved by implementing TV-detection: 12 • • Automatic video start by polling the video line periodically. Automatic video stop if the TV (or other equipment) is disconnected. Proper implementation allows to significantly simplify the user interface.
