Product details
Overview
TLC2262CPWR from Texas Instruments is a dual rail-to-rail output operational amplifier in TSSOP-8 package, designed for precision signal conditioning in single- or split-supply systems. It delivers 0.55 V/µs slew rate, 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current, and supports ±2.2 V to ±8 V operation - ideal for interfacing with low-voltage ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2262CPWR datasheet, TLC2262CPWR pinout, TLC2262CPWR application, or TLC2262CPWR equivalent, key selection criteria include its rail-to-rail output swing (enabling full dynamic range utilization), ultra-low input bias current (critical for high-impedance piezoelectric transducer interfaces), and guaranteed performance across 0°C to 70°C ambient temperature.
Technical Context
The TLC2262CPWR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (12 nV/√Hz). Its input stage includes common-mode voltage range extending to the negative rail, enabling true single-supply operation down to 4.4 V total supply.
It features fully specified performance for both single-supply (e.g., +5 V) and split-supply (e.g., ±5 V) configurations, with input offset voltage ≤2.5 mV (max) and CMRR ≥70 dB over temperature. The device is optimized as a performance upgrade path from TS27M2 and TLC27M2 families, offering improved noise, offset, and output drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide-range industrial and portable designs with single- or dual-rail supplies. |
| Input Bias Current | 1 pA (typ) - enables accurate amplification of signals from high-impedance sources like piezo sensors. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLC27M2, critical for low-level analog signal integrity. |
| Slew Rate | 0.55 V/µs (typ) - sufficient for audio and medium-speed data acquisition without distortion. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD–0.1 V output range, maximizing ADC input utilization. |
| Supply Current | 500 µA max per amplifier - enables dual-channel precision amplification in space-constrained, low-power systems. |
| Input Offset Voltage | 2.5 mV max (C-suffix, 0°C to 70°C) - suitable for moderate-accuracy DC-coupled applications without trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher slew rate (1.5 V/µs), higher supply current (650 µA), wider input voltage range (to VDD– +0.2 V), but higher input bias current (10 nA). | Better suited for higher-speed multiplexed sensor arrays requiring faster settling. | Select TLV2432IDR when bandwidth >1 MHz or settling time <1 µs is required; avoid for ultra-high-Z sources. |
| OPA2333AIDR | Zero-drift architecture, 12 µV max VIO, 0.15 µV/°C drift, but higher supply current (17 µA per amp) and no rail-to-rail output (clips ~200 mV from rails). | Ideal for DC-critical applications like precision weight scales or calibration equipment. | Choose OPA2333AIDR only when sub-20 µV offset and near-zero drift outweigh rail-to-rail output necessity. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262CPWR uniquely balances ultra-low input bias current, rail-to-rail output, and micropower consumption - making it optimal for battery-operated, high-impedance sensor interfaces where speed and zero-drift are secondary to input fidelity and supply efficiency.

FAQ
What is the maximum operating supply voltage for the TLC2262CPWR?
The TLC2262CPWR supports a maximum total supply voltage of 16 V in single-supply mode (e.g., 0 V to 16 V) or ±8 V in split-supply mode. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD– ≥ –8 V; exceeding these risks permanent damage. Operation above ±8 V is not characterized or guaranteed.
Does the TLC2262CPWR support true rail-to-rail input common-mode range?
No - the TLC2262CPWR provides rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail (VDD–/GND), not to the positive rail. At VDD = 5 V, VICR is specified as 0 V to 3.5 V (full range), meaning the input cannot safely exceed VDD–1.5 V. This differs from true rail-to-rail input op-amps.
Can the TLC2262CPWR drive a 10 kΩ load while maintaining rail-to-rail output?
Yes - the TLC2262CPWR guarantees rail-to-rail output swing into loads ≥10 kΩ at room temperature. Electrical characteristics show VOH ≥4.82 V and VOL ≤0.15 V at VDD = 5 V with RL = 50 kΩ; performance degrades gradually below 10 kΩ but remains functional down to 2 kΩ per the output current specification (±50 mA).
Is the TLC2262CPWR pin-compatible with the TLC2262CP or TLC2262CD?
Yes - the TLC2262CPWR (TSSOP-8), TLC2262CP (PDIP-8), and TLC2262CD (SOIC-8) share identical pinout and electrical functionality. All three packages implement the same dual op-amp topology with matching pin assignments: Pin 1 (1IN–), Pin 2 (1IN+), Pin 3 (1OUT), Pin 4 (GND), Pin 5 (VDD+), Pin 6 (2IN+), Pin 7 (2IN–), Pin 8 (2OUT).
What is the typical input offset voltage drift over temperature for the TLC2262CPWR?
The TLC2262CPWR has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C over 25°C to 70°C. This means that for a 45°C ambient shift, typical VIO drift is ≤90 µV - well within the 2.5 mV maximum limit. Long-term drift is specified at 0.003 µV/month under accelerated life testing conditions.
