Texas Instruments TLV1702AIDGK

Overview

TLV1702AIDGK from Texas Instruments is a dual-channel, rail-to-rail input microPower comparator with open-collector outputs, 55 µA per channel quiescent current, 560 ns low-to-high propagation delay at 2.2 V supply, and –40°C to +125°C industrial temperature range. It enables overvoltage detection and window comparator circuits in space-constrained industrial sensor interfaces.

For engineers reviewing the TLV1702AIDGK datasheet, TLV1702AIDGK pinout, TLV1702AIDGK application, or TLV1702AIDGK equivalent, key selection criteria include its 2.2–36 V wide supply range, rail-to-rail input stage, 300 µV typical input offset voltage, stable propagation delay across temperature, and VSSOP-8 package compatibility with high-density PCB layouts.

Technical Context

The TLV1702AIDGK implements two independent comparators with rail-to-rail input stages that operate without phase inversion even when inputs exceed supply rails. Its open-collector outputs support wired-OR configurations and flexible pull-up voltage selection up to +36 V above the negative supply.

Designed for low-power industrial monitoring, it maintains 560 ns (low-to-high) and 460 ns (high-to-low) propagation delay across –40°C to +125°C and 2.2 V to 36 V supply, with input bias current ≤15 nA and input offset voltage drift ≤20 µV/°C.

FAQ

What is the maximum supply voltage rating for TLV1702AIDGK?

The absolute maximum supply voltage for TLV1702AIDGK is +40 V (or ±20 V), but the recommended operating range is +2.2 V to +36 V (±1.1 V to ±18 V). Exceeding +40 V risks permanent damage. The device is designed for robust operation in 24 V industrial systems, and its open-collector outputs tolerate up to +36 V above V– regardless of the supply voltage applied to V+ and V–.

Does TLV1702AIDGK support dual-supply operation?

Yes, TLV1702AIDGK supports dual-supply operation from ±1.1 V to ±18 V. When used with dual supplies, V+ connects to the positive rail and V– to the negative rail; inputs and outputs reference this split supply. The rail-to-rail input stage functions correctly across the full range, and the open-collector outputs sink current relative to V–, enabling compatibility with bipolar signal chains in motor control or audio monitoring applications.

Can TLV1702AIDGK drive a 5 V logic input directly?

No, TLV1702AIDGK cannot drive a 5 V logic input directly because it has open-collector outputs with no internal pull-up. To interface with 5 V logic, an external pull-up resistor must connect OUT A or OUT B to a 5 V rail. The output will then sink current when active (LOW) and float when inactive (HIGH), allowing clean level translation. The device itself does not source current, so proper external pull-up sizing (e.g., 4.7 kΩ) is required for reliable 5 V logic-level signaling.

What is the input offset voltage specification for TLV1702AIDGK over temperature?

The input offset voltage for TLV1702AIDGK is specified as ±5.5 mV maximum over the full –40°C to +125°C operating range, with ±300 µV typical at +25°C. Its offset voltage drift is ±20 µV/°C max, meaning worst-case cumulative offset shift across the full temperature span remains within the ±5.5 mV limit. This performance supports precision threshold detection in automotive and industrial environments where ambient temperature varies widely.

Is TLV1702AIDGK pin-compatible with other packages in the TLV170x family?

No, TLV1702AIDGK (VSSOP-8) is not pin-compatible with other TLV170x dual-channel variants such as TLV1702RUG (X2QFN-8), which shares the same pin count but differs in pin assignment and thermal pad configuration. The VSSOP-8 (DGK) and X2QFN-8 (RUG) packages have distinct pinouts-e.g., IN+ B is on pin 6 in DGK but pin 5 in RUG. Board layout must match the specific package; substitution requires PCB redesign unless verified as mechanically and electrically equivalent per TI's package addendum.
