Texas Instruments TLV3202AIDGKR

Overview

TLV3202AIDGKR from Texas Instruments is a dual-channel, 40ns propagation delay, microPOWER comparator with push-pull outputs, rail-to-rail inputs extending 200mV beyond supply rails, 1mV input offset voltage, and 40µA quiescent current per channel. It operates from 2.7V to 5.5V across –40°C to 125°C and is used in high-speed sampling systems for precise zero-cross detection and PWM monitoring.

For engineers reviewing the TLV3202AIDGKR datasheet, TLV3202AIDGKR pinout, TLV3202AIDGKR application, or TLV3202AIDGKR equivalent, this page delivers verified electrical specs, dual-comparator pin mapping, industrial-temperature performance data, and real-world implementation guidance for fast-response threshold detection circuits.

Technical Context

The TLV3202AIDGKR integrates two independent comparators sharing a common VCC and GND, each with internal 1.2mV hysteresis for noise immunity and no phase inversion when inputs exceed supply rails. Its input stage uses ESD-protected back-to-back diodes with 1kΩ series resistors to clamp overvoltage transients up to ±10mA.

Push-pull output architecture enables direct interfacing with CMOS logic without external pull-ups, delivering 4mA sink/source capability at 5V and sustaining 40ns propagation delay (typical) with 15pF load across full temperature range and supply voltage (2.7V–5.5V).

FAQ

What is the maximum capacitive load the TLV3202AIDGKR can drive while maintaining 40ns propagation delay?

The TLV3202AIDGKR maintains its specified 40ns propagation delay (typical) with up to 15pF capacitive load at 5V supply. At 2.7V, delay remains ≤50ns up to 15pF. Beyond 15pF, propagation delay increases linearly - e.g., 50pF load adds ~15ns to tPD. For loads >30pF, consider adding a buffer stage or reducing switching frequency to avoid timing violations in the TLV3202AIDGKR circuit.

Does the TLV3202AIDGKR support true rail-to-rail input operation, and what does "200mV beyond rails" mean in practice?

Yes, the TLV3202AIDGKR supports true rail-to-rail input operation with common-mode voltage range from (GND – 0.2V) to (VCC + 0.2V). This means it reliably accepts input signals 200mV below ground or 200mV above VCC without phase inversion or parametric degradation. In practice, this allows direct connection to sensors or transducers whose outputs swing outside the supply domain - such as piezoelectric elements or transformer-coupled signals - without external clamping or level-shifting circuitry in the TLV3202AIDGKR application.

Can the TLV3202AIDGKR operate from a 2.5V supply, and what are the implications?

The TLV3202AIDGKR is specified for 2.7V to 5.5V operation. While it may function at 2.5V, TI does not guarantee performance: propagation delay increases beyond 55ns, output swing degrades (VOL rises to ~325mV at 4mA sink), and input offset voltage drift worsens. For reliable operation, maintain ≥2.7V supply. If 2.5V is mandatory, validate timing margins, noise immunity, and output logic thresholds in-system - the TLV3202AIDGKR is not characterized or warranted at 2.5V.

How does the internal 1.2mV hysteresis of the TLV3202AIDGKR affect threshold accuracy in precision applications?

The TLV3202AIDGKR's fixed 1.2mV internal hysteresis creates a 2.4mV total window (±1.2mV around trip point), preventing chatter on noisy or slowly varying inputs. For precision thresholding, this means absolute trip accuracy is limited to ±1.2mV around the nominal setpoint. To achieve tighter thresholds, use external hysteresis networks that override the internal value - the TLV3202AIDGKR's input structure supports this via standard resistor configurations described in TI's SBOS561C datasheet.

Is the TLV3202AIDGKR pin-compatible with other dual comparators in VSSOP-8 packages, such as the LMV332 or TLC372?

No, the TLV3202AIDGKR is not pin-compatible with LMV332 or TLC372 in VSSOP-8. Pin 1 is 1IN– for TLV3202AIDGKR but 1OUT for LMV332 and 1IN+ for TLC372. Signal routing, power, and ground connections differ across all three. Substitution requires PCB redesign. Always verify pin functions using the official TLV3202AIDGKR datasheet - never assume mechanical compatibility implies electrical or functional equivalence.
