Texas Instruments TLV2341ID

Overview

TLV2341ID from Texas Instruments is a programmable low-voltage LinCMOS™ operational amplifier in an 8-pin SOIC (D) package, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It features bias-select programmability (17 µA / 250 µA / 1.5 mA), rail-to-rail output swing including the negative rail, and 10¹² Ω typical input impedance - enabling direct interface with high-impedance sensors in portable battery-powered instrumentation.

For engineers reviewing the TLV2341ID datasheet, TLV2341ID pinout, TLV2341ID application, or TLV2341ID equivalent, key selection criteria include its programmable supply current vs. ac performance tradeoff, guaranteed common-mode input range extending below ground, low 25 nV/√Hz noise in high-bias mode, and compatibility with 3-V and 5-V systems requiring stable low-power amplification.

Technical Context

The TLV2341ID implements a silicon-gate LinCMOS™ process enabling ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance, critical for precision sensor signal conditioning. Its bias-select architecture uses a dedicated terminal to set one of three internal current modes - directly controlling slew rate (0.02–2.1 V/µs), unity-gain bandwidth (27–790 kHz), and noise density (68–25 nV/√Hz).

Input stage design supports common-mode voltage down to –0.2 V (at VDD = 3 V) and up to VDD – 1 V, while output swings to within 120 mV of GND and 190 mV of VDD under 1-mA load. ESD protection per MIL-STD-883C Method 3015.2 (2000 V) and latch-up immunity are built-in.

FAQ

What is the maximum supply voltage rating for TLV2341ID?

The absolute maximum supply voltage for TLV2341ID is 8 V. Operation above this level risks permanent damage. Recommended operating range is 2 V to 8 V, with full characterization at 3 V and 5 V. At 8 V, thermal dissipation must remain within the D-package derating limit of 5.8 mW/°C above 25°C ambient.

How does the BIAS SELECT pin configure operating modes in TLV2341ID?

The BIAS SELECT pin on TLV2341ID sets supply current and ac performance by voltage level: GND selects low-bias mode (17 µA, 0.02 V/µs), VDD/2 selects medium-bias (250 µA, 0.38 V/µs), and VDD selects high-bias (1.5 mA, 2.1 V/µs). A resistive divider is required for VDD/2 in single-supply systems.

Can TLV2341ID drive capacitive loads without instability?

TLV2341ID is stable driving ≤20 pF capacitive loads in high-bias mode with 10-kΩ load. For larger loads, external isolation resistor (≥100 Ω) between output and capacitance is required. Phase margin drops from 46° to <30° at 100 pF, risking oscillation without compensation.

What is the input common-mode voltage range of TLV2341ID at 3-V supply?

At VDD = 3 V, TLV2341ID supports a common-mode input range from –0.2 V to 1.8 V (VDD – 1.2 V) at 25°C. This extends below ground, enabling true single-supply operation with ground-referenced inputs - critical for sensor interfaces without dual supplies.

Does TLV2341ID require external offset nulling in precision applications?

TLV2341ID includes dedicated OFFSET N1 and OFFSET N2 pins for external nulling via a 10-kΩ potentiometer. While input offset voltage is typically 0.6 mV (max 10 mV), nulling reduces residual error to <100 µV - essential for 16-bit+ data acquisition systems where offset drift dominates total error budget.
