Texas Instruments TLV1702AIDGKR

Overview

TLV1702AIDGKR 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 designs in space-constrained industrial sensor interfaces.

For engineers reviewing the TLV1702AIDGKR datasheet, TLV1702AIDGKR pinout, TLV1702AIDGKR application, or TLV1702AIDGKR equivalent, key selection criteria include its 2.2–36 V wide supply range, rail-to-rail input stage, stable propagation delay vs temperature, low input offset voltage (±300 µV typ), and VSSOP-8 package compatibility with high-density PCB layouts.

Technical Context

The TLV1702AIDGKR implements a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, supporting accurate threshold detection near V+ or GND. Its open-collector output allows flexible pull-up to voltages up to +36 V above the negative supply, independent of device supply voltage.

Each comparator channel operates with matched switching characteristics: 560 ns low-to-high and 460 ns high-to-low propagation delay (typical, 100 mV overdrive), 365 ns rise time, and 240 ns fall time into 15 pF load - enabling precise timing-critical comparisons across its full 2.2–36 V supply range.

FAQ

What is the maximum supply voltage rating for TLV1702AIDGKR?

The absolute maximum supply voltage for TLV1702AIDGKR 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 maintains specified performance across its full 2.2–36 V range, including propagation delay stability and input common-mode coverage.

Does TLV1702AIDGKR support dual-supply operation?

Yes, TLV1702AIDGKR supports dual-supply operation from ±1.1 V to ±18 V. Its inputs are rail-to-rail and fully functional with symmetric or asymmetric dual supplies. The V+ pin connects to the most positive supply, and V– to the most negative supply; the open-collector outputs can be pulled up to any voltage ≤ +36 V above V–, regardless of the comparator's own supply rails.

Can TLV1702AIDGKR drive a 10 kΩ pull-up resistor to 5 V while maintaining specification?

Yes, TLV1702AIDGKR can drive a 10 kΩ pull-up to 5 V. Its output sink capability is rated for 20 mA continuous, so with 5 V pull-up the worst-case sink current is 500 µA - well within specification. Propagation delay and rise/fall times remain within datasheet limits (tpLH = 560 ns typ) under this load, as confirmed by switching characteristics testing at RPULLUP = 5.1 kΩ and CL = 15 pF.

What is the input offset voltage drift of TLV1702AIDGKR over temperature?

The input offset voltage drift of TLV1702AIDGKR is ±4 µV/°C to ±20 µV/°C (typ to max) over –40°C to +125°C. This low drift ensures threshold accuracy remains stable across thermal cycling - critical for applications like battery voltage monitoring or precision window detection where offset drift could cause false trips.

Is TLV1702AIDGKR pin-compatible with other packages in the TLV170x family?

No, TLV1702AIDGKR (VSSOP-8) is not pin-compatible with TLV1702 variants in X2QFN-8 (RUG) or other footprints. While electrical functionality is identical, the VSSOP-8 (DGK) pinout differs from RUG: DGK uses pins 1–3–2–4–5–6–7–8 for OUTA–IN−A–IN+A–V−–V+–IN+B–IN−B–OUTB, whereas RUG assigns different pin numbers to the same functions. Always verify layout against the DGK-specific pin diagram.
