Texas Instruments TLV3402IDGKG4

Overview

TLV3402IDGKG4 from Texas Instruments is a dual-channel nanopower open-drain comparator optimized for ultra-low-power battery-operated systems. It draws only 470 nA per channel at 2.7 V, supports supply voltages from 2.5 V to 16 V, and features rail-to-rail input range (–0.1 V to VCC + 5 V) with reverse battery protection up to 18 V - enabling use in portable medical devices and wireless security sensors.

For engineers reviewing the TLV3402IDGKG4 datasheet, TLV3402IDGKG4 pinout, TLV3402IDGKG4 application, or TLV3402IDGKG4 equivalent, key selection criteria include nanoscale quiescent current, extended industrial temperature operation (–40°C to +125°C), VSSOP-8 package compatibility, and open-drain output stage requiring external pull-up for logic-level translation.

Technical Context

The TLV3402IDGKG4 implements a CMOS input stage with differential pair architecture enabling input common-mode voltage extension beyond VCC by 5 V and down to –0.1 V. Its open-drain output stage interfaces directly with mixed-voltage logic domains via configurable pull-up voltage, supporting both single-supply (2.5–16 V) and split-supply (±1.25 V to ±8 V) configurations.

Designed for low-noise threshold detection, it delivers 250 µV typical input offset voltage, 55–88 dB CMRR across supply range, and propagation delays of 55–300 µs depending on overdrive level - making it suitable for precision wake-up circuits where input signal slew rates are slow and power budget is sub-1 µA per channel.

FAQ

What is the maximum supply voltage rating for TLV3402IDGKG4?

The TLV3402IDGKG4 has an absolute maximum supply voltage of 17 V, with recommended operating range from 2.5 V to 16 V. Exceeding 17 V risks permanent damage, and operation above 16 V voids specification guarantees. The device also withstands reverse battery conditions up to –18 V on VCC, a key reliability feature for portable equipment.

Does TLV3402IDGKG4 support rail-to-rail input operation?

Yes, TLV3402IDGKG4 supports true rail-to-rail input operation with a common-mode range from –0.1 V to VCC + 5 V. This allows inputs to swing 5 V above the positive supply rail or 100 mV below ground - enabling direct sensing of battery voltage or transducer outputs without external level-shifting circuitry.

What package type is used for TLV3402IDGKG4?

TLV3402IDGKG4 uses the DGK package: an 8-pin VSSOP with 3.00 mm × 3.00 mm body size and 0.65 mm lead pitch. This ultra-small outline package is surface-mount compatible and optimized for high-density PCB layouts in portable electronics.

Can TLV3402IDGKG4 drive standard CMOS logic directly?

No - TLV3402IDGKG4 features open-drain outputs and cannot drive CMOS logic high without an external pull-up resistor. A 1 MΩ pull-up to VCC or another logic rail is specified in the datasheet to meet timing and voltage-swing requirements; value selection balances speed, power, and noise immunity.

What is the typical input offset voltage of TLV3402IDGKG4?

The typical input offset voltage of TLV3402IDGKG4 is 250 µV at 25°C, with a maximum of 4400 µV over the full –40°C to +125°C industrial temperature range. This low offset enables precise threshold detection in applications like 1.25 V reference monitoring without trimming or calibration.
