Texas Instruments TLV2341IDR

Overview

TLV2341IDR from Texas Instruments is a programmable low-voltage LinCMOS™ operational amplifier in an 8-pin SOIC (D) package, supporting single-supply operation from 2 V to 8 V across –40°C to 85°C. It features bias-select functionality enabling three supply current modes (17 µA / 250 µA / 1.5 mA), rail-to-rail output swing down to GND, and input common-mode range extending below the negative rail - ideal for battery-powered sensor signal conditioning.

For engineers reviewing the TLV2341IDR datasheet, TLV2341IDR pinout, TLV2341IDR application, or TLV2341IDR equivalent, key selection criteria include its programmable bias architecture, guaranteed 8 mV max input offset voltage at 25°C, high input impedance (>10¹² Ω), ESD protection up to 2000 V, and compatibility with 3-V/5-V systems requiring low quiescent power without sacrificing ac performance.

Technical Context

The TLV2341IDR implements a silicon-gate LinCMOS™ process enabling ultra-low input bias currents (<1 pA typ), excellent dc precision, and stable offset voltage drift (2.7 µV/°C max). Its bias-select pin allows dynamic configuration of internal current sources to trade off slew rate (0.02–2.1 V/µs), unity-gain bandwidth (27–790 kHz), and noise (68–25 nV/√Hz) while maintaining consistent input/output voltage ranges.

Input stage design supports common-mode voltages from –0.2 V to VDD–1 V at 25°C, and output drives to within 120 mV of GND (IOL = 1 mA) and 1.75 V of VDD (IOH = –1 mA) at 3 V supply. Internal ESD protection and latch-up immunity meet MIL-STD-883C requirements, enabling robust deployment in portable instrumentation and industrial analog front-ends.

FAQ

What supply voltage range does the TLV2341IDR support?

The TLV2341IDR operates from 2 V to 8 V across the full industrial temperature range (–40°C to 85°C), fully characterized at both 3 V and 5 V. This wide range allows direct integration into single-cell Li-ion (3.0–3.7 V), two-cell alkaline (2.4–3.2 V), and standard 5-V systems without external regulators - a key advantage for space-constrained portable designs where TLV2341IDR replaces multiple fixed-voltage op-amps.

How does the BIAS SELECT pin configure TLV2341IDR performance?

The BIAS SELECT pin on TLV2341IDR sets one of three internal bias currents: grounding selects 17 µA (low-bias), connecting to mid-rail selects 250 µA (medium-bias), and tying to VDD selects 1.5 mA (high-bias). This directly controls slew rate (0.02–2.1 V/µs), unity-gain bandwidth (27–790 kHz), and input noise (68–25 nV/√Hz) - enabling TLV2341IDR to adapt ac performance to real-time system demands without hardware changes.

Can TLV2341IDR drive analog-to-digital converter (ADC) inputs effectively?

Yes - TLV2341IDR's rail-to-rail output swing (within 120 mV of GND at 3 V) and low output impedance (<1 Ω) make it well-suited for driving SAR and delta-sigma ADC inputs. Its 2.1 V/µs slew rate in high-bias mode settles 12-bit codes in <1 µs, and the 10¹² Ω input impedance prevents loading of high-Z sensor sources feeding the TLV2341IDR itself - ensuring full dynamic range utilization in precision data acquisition systems.

What is the maximum input common-mode voltage for TLV2341IDR at 3 V supply?

At VDD = 3 V, the TLV2341IDR supports a common-mode input voltage range of –0.2 V to 1.8 V at 25°C, verified per datasheet Table 1. This extends 0.2 V below GND - enabling direct high-side current sensing using a shunt resistor referenced to VDD, and eliminating the need for level-shifting circuitry that would add error and board area in designs using TLV2341IDR.

Does TLV2341IDR require external offset nulling components?

TLV2341IDR provides dedicated OFFSET N1 and OFFSET N2 pins for optional external nulling via a 10-kΩ potentiometer, but it is fully functional without them. The device guarantees ≤8 mV input offset voltage at 25°C and ≤10 mV over –40°C to 85°C - sufficient for most portable sensor interfaces. External nulling is only needed in applications demanding <1 mV offset, such as high-resolution weigh scales or laboratory-grade instrumentation using TLV2341IDR.
