Rail-to-rail input, low offset (5μV typ), low noise (7.5nV/√Hz), quiescent current less than 1mA max, and a 5.5MHz bandwidth make this part very attractive for a variety of precision and portable applications. In addition, this device has a reasonably wide supply range with excellent PSRR, making it attractive for applications that run directly from batteries without regulation. The OPA376 (single version) is available in MicroSIZE SC70-5, SOT23-5, and SO-8 packages. The OPA2376 (dual) is offered in the MSOP-8 and SO-8 packages. The OPA4376 (quad) is offered in a TSSOP-14 package. All versions are specified for operation from –40°C to +125°C.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Many of the specifications apply from –40°C to +125°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in the Typical Characteristics. COMMON-MODE VOLTAGE RANGE The input common-mode voltage range of the OPA376 series extends 100mV beyond the supply rails. The offset voltage of the amplifier is very low, from approximately (V–) to (V+) – 1V, as shown in Figure 23. The offset voltage increases as common-mode voltage exceeds (V+) –1V. Common-mode rejection is specified from (V–) to (V+) – 1.3V. 3 2 GENERAL LAYOUT GUIDELINES For best operational performance of the device, good printed circuit board (PCB) layout practices are required. Low-loss, 0.1μF bypass capacitors must be connected between each supply pin and ground as close to the device as possible. A single bypass capacitor from V+ to ground is applicable to single-supply applications. Output Voltage (mV) 1 0 -1 -2 BASIC AMPLIFIER CONFIGURATIONS The OPA376 family is unity-gain stable. It does not exhibit output phase inversion when the input is overdriven. A typical single-supply connection is shown in Figure 22. The OPA376 is configured as a basic inverting amplifier with a gain of –10V/V. This single-supply connection has an output centered on the common-mode voltage, VCM. For the circuit shown, this voltage is 2.5V, but may be any value within the common-mode input voltage range.

Offset and Common-Mode Voltage INPUT AND ESD PROTECTION The OPA376 family incorporate internal electrostatic discharge (ESD) protection circuits on all pins. In the case of input and output pins, this protection primarily consists of current steering diodes connected between the input and power-supply pins. These ESD protection diodes also provide in-circuit, input overdrive protection, provided that the current is limited to 10mA as stated in the Absolute Maximum Ratings. Figure 24 shows how a series input resistor may be added to the driven input to limit the input current. The added resistor contributes thermal noise at the amplifier input and its value should be kept to a minimum in noise-sensitive applications. +5V R1 1kW OPA376 VIN C1 100nF VOUT VCM = 2.5V IOVERLOAD 10mA max V+ OPA376 VOUT Figure 22.

As with all op amps, there may be specific instances where the OPAx376 can become unstable, leading to oscillation. The particular op amp circuit configuration, layout, gain and output loading are some of the factors to consider when establishing whether an amplifier will be stable in operation. An op amp in the unity-gain (+1V/V) buffer configuration and driving a capacitive load exhibits a greater tendency to be unstable than an amplifier operated at a higher noise gain. The capacitive load, in conjunction with the op amp output resistance, creates a pole within the feedback loop that degrades the phase margin. The degradation of the phase margin increases as the capacitive loading increases. The OPAx376 in a unity-gain configuration can directly drive up to 250pF pure capacitive load. Increasing the gain enhances the ability of the amplifier to drive greater capacitive loads (see the typical characteristic plot, Small-Signal Overshoot vs Capacitive Load. In unity-gain configurations, capacitive load drive can be improved by inserting a small (10Ω to 20Ω) resistor, RS, in series with the output, as shown in Figure 25. This resistor significantly reduces ringing while maintaining dc performance for purely capacitive loads. However, if there is a resistive load in parallel with the capacitive load, a voltage divider is created, introducing a gain error at the output and slightly reducing the output swing. The error introduced is proportional to the ratio RS/RL, and is generally negligible at low output current levels. V+ RS OPA376 VIN 10W to 20W RL CL VOUT ACTIVE FILTERING The OPA376 series is well-suited for filter applications requiring a wide bandwidth, fast slew rate, low-noise, single-supply operational amplifier. Figure 26 shows a 50kHz, 2nd-order, low-pass filter. The components have been selected to provide a maximally-flat Butterworth response. Beyond the cutoff frequency, roll-off is –40dB/dec. The Butterworth response is ideal for applications requiring predictable gain characteristics such as the anti-aliasing filter used ahead of an analog-to-digital converter (ADC).

The cable serves double duty, carrying both the differential output signal from, and dc power to the microphone amplifier stage. An OPA2376 serves as a single-ended input, to differential output amplifier with a 6dB gain.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
