Texas Instruments TLV2402IP

Overview

TLV2402IP from Texas Instruments is a dual, rail-to-rail input/output micro-power operational amplifier with reverse battery protection up to 18 V. It delivers 880 nA/channel supply current, 5.5 kHz gain bandwidth, and operates from 2.5 V to 16 V. Its input common-mode range extends to VCC + 5 V and –0.1 V, enabling use in Li-ion–powered sensor front-ends and battery-monitoring circuits.

For engineers reviewing the TLV2402IP datasheet, TLV2402IP pinout, TLV2402IP application, or TLV2402IP equivalent, this page provides verified specifications, package mapping to 8-pin PDIP, real-world application context for ultra-low-power analog signal conditioning, and validated alternative options for industrial-grade single-supply op-amp selection.

Technical Context

The TLV2402IP uses a hybrid PNP/NPN input stage to achieve rail-to-rail input operation and tolerate inputs up to VCC + 5 V without damage. Its reverse battery protection relies on internal Schottky diode clamping, limiting reverse supply current to ≤50 nA at –18 V and 25°C.

DC precision is maintained via low input offset voltage (390 µV typical), high CMRR (120 dB), and low input bias current (100 pA typical). The amplifier is unity-gain stable with capacitive loads up to 100 pF and exhibits 60° phase margin under standard test conditions (RL = 500 kΩ, CL = 100 pF).

FAQ

What is the maximum supply voltage for TLV2402IP?

The absolute maximum supply voltage for TLV2402IP is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation at 16 V is fully characterized per datasheet SLOS244B, with guaranteed performance including 120 dB CMRR and 130 V/mV open-loop gain at 25°C. Exceeding 16 V risks parametric degradation or latch-up.

Does TLV2402IP support rail-to-rail input beyond the positive supply rail?

Yes, TLV2402IP supports input voltages up to VCC + 5 V without damage or phase inversion. This is enabled by its dual-input-stage architecture (PNP + NPN followers), allowing direct interfacing with overvoltage-safe transducers or biased sensor outputs. At VCC + 5 V, input bias current increases but remains within safe limits per datasheet Section 13.

What is the reverse battery protection capability of TLV2402IP?

TLV2402IP provides reverse battery protection up to –18 V. Under –18 V reverse supply with grounded inputs and open outputs, reverse supply current is typically 50 nA at 25°C - low enough to prevent damage or excessive power drain. This eliminates the need for external series diodes in battery-powered equipment subject to installation errors.

Can TLV2402IP drive capacitive loads?

TLV2402IP is unity-gain stable with capacitive loads up to 100 pF, as confirmed by phase margin ≥60° and gain margin ≥15 dB in datasheet Figure 24 and 25. For loads >100 pF, external isolation resistance (e.g., 100 Ω in series with output) is required to maintain stability. Layout parasitics must be minimized to avoid unintended resonance.

What is the input offset voltage specification for TLV2402IP over temperature?

TLV2402IP has a maximum input offset voltage of 1500 µV across the full industrial temperature range (–40°C to 125°C), with a typical value of 390 µV at 25°C. Its offset drift is 3 µV/°C, resulting in worst-case drift of ±375 µV over the full range - making it suitable for precision DC-coupled applications requiring <2 mV total error budget.
