Device Information(1) Supply Current vs Supply Voltage 700 The TLV340x has a minimum operating supply voltage of 2.7 V over the extended industrial temperature range (TA = –40°C to +125°C), while having an input common-mode range of –0.1 to VCC + 5 V. The low supply current makes it an ideal choice for battery-powered portable applications where quiescent current is the primary concern. Reverse battery protection guards the amplifier from an overcurrent condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the positive supply rail without damage to the device.

Having a minimum operating supply voltage of 2.7 V over the extended industrial temperature range (TA = –40°C to +125°C), while having an input common-mode range of –0.1 to VCC + 5 V makes this device ideal for batterypowered and wireless handset applications. 8.2 Functional Block Diagram VCC IN+ OUT IN± GND Copyright © 2016, Texas Instruments Incorporated 8.3 Feature Description 8.3.1 Operating Voltage The TLV340x comparators are specified for use on a single supply from 2.5 V to 16 V (or a dual supply from ±1.25 V to ±16 V) over a temperature range of −40°C to +125°C. 8.3.2 Setting the Threshold Using a low-power, stable reference is important when setting the transition point for the TLV340x devices.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information Many applications require the detection of a signal (voltage or current) that exceeds a particular threshold voltage or current. Using a comparator to make that threshold detection is the easiest, lowest power and highest speed way to make a threshold detection. 9.2 Typical Application 5V Input voltage IN+ 1M RPULL-UP VCC Output voltage OUT 5V REF3312 IN± GND 1.25 V threshold voltage Copyright © 2016, Texas Instruments Incorporated Figure 16. 1.25-V Threshold Detector 9.2.1 Design Requirements • • • • Detect when a signal is above or below 1.25 V Operate from a single 5-V power supply Rail-to-rail input voltage range from 0 to 5 V Rail-to-rail output voltage range from 0 to 5 V 9.2.2 Detailed Design Procedure The input voltage range in the circuit illustrated in Figure 16 is limited only by the power supply applied to the TV3401. In this example with the selection of a 5-V, single-supply power supply, the input voltage range is limited to 0 to VS + 5 V, or 0 to 10 V. The threshold voltage of 1.25 V can de derived in a variety of ways. As the TLV3401 is a very low-power device, it is desirable to also use very low power to create the threshold voltage. The REF3312 series voltage reference is selected for its stable output voltage of 1.25 V and its low power consumption of only 3.9 µA. The TLV3401 is an open-drain output comparator, requiring a pullup resistor from output to the power supply. Proper selection of the pullup resistor value requires maximizing the output voltage swing while at the same time minimizing power dissipated in the resistor when the output voltage is low. Too small of a pullup resistor can result in too much power dissipation, while too large of a pullup resistor can result in slower response times. The TLV3401 is fully specified with a 1-MΩ pullup resistor and using a 1-MΩ pullup resistor results in meeting the performance specifications listed in the Electrical Characteristics.

Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in Typical Characteristics. 11 Layout 11.1 Layout Guidelines Figure 18 shows the typical connections for the TLV340x. To minimize supply noise, power supplies must be capacitively decoupled by a 0.01-µF ceramic capacitor in parallel with a 10-µF electrolytic capacitor. Comparators are very sensitive to input noise. Proper grounding (the use of a ground plane) helps to maintain the specified performance of the TLV340x family. For best results, maintain the following layout guidelines: 1. Use a printed-circuit board (PCB) with a good, unbroken low-inductance ground plane. 2. Place a decoupling capacitor (0.1-µF ceramic, surface-mount capacitor) as close as possible to VCC. 3. On the inputs and the output, keep lead lengths as short as possible to avoid unwanted parasitic feedback around the comparator. Keep inputs away from the output. 4. Solder the device directly to the PCB rather than using a socket. 5. For slow-moving input signals, take care to prevent parasitic feedback. A small capacitor (1000 pF or less) placed between the inputs can help eliminate oscillations in the transition region. This capacitor causes some degradation to propagation delay when the impedance is low. The top-side ground plane runs between the output and inputs. 6. The ground pin ground trace runs under the device up to the bypass capacitor, shielding the inputs from the outputs. 11.2 Layout Example Power supply 0.01 µF 10 F V+ RPULL-UP +IN OUT ± IN OUT RPULL-UP Power supply 1 5 0.01 µF 10 F 2 ± + 3 4 Not to scale +IN ±IN Copyright © 2016, Texas Instruments Incorporated Figure 18.
