Product details
Overview
TLC2262QDG4 from Texas Instruments is a dual rail-to-rail output operational amplifier designed for precision signal conditioning in automotive and industrial systems. It delivers 12 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current, and full rail-to-rail output swing with ±2.2 V to ±8 V supply operation - enabling high-fidelity analog front-ends in battery-powered sensor interfaces.
For engineers reviewing the TLC2262QDG4 datasheet, TLC2262QDG4 pinout, TLC2262QDG4 application, or TLC2262QDG4 equivalent, key selection criteria include its Q-temp automotive qualification (–40°C to 125°C), low-noise CMOS architecture, rail-to-rail output capability for ADC interfacing, and compatibility with single- or split-supply configurations in space-constrained designs.
Technical Context
The TLC2262QDG4 uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) while maintaining rail-to-rail output swing across the full supply range. Its input stage includes common-mode voltage range extending to the negative rail, supporting true single-supply operation without level-shifting circuitry.
It features a unity-gain stable architecture with 0.55 V/µs slew rate (typ), 0.71 MHz gain-bandwidth product, and 56° phase margin - optimized for stable closed-loop performance in low-power instrumentation and transducer signal chains where dynamic range and DC precision are critical.
Key Specifications

| Supply Voltage Range | ±2.2 V to ±8 V - supports wide-input industrial and automotive power rails without external regulation |
| Input Bias Current | 1 pA typ - enables high-impedance source interfacing (e.g., piezoelectric sensors) without significant error |
| Input Noise Voltage | 12 nV/√Hz at 1 kHz - ensures minimal added noise in low-level signal amplification stages |
| Output Swing | Rail-to-rail - maximizes dynamic range when driving SAR or sigma-delta ADCs directly |
| Supply Current | 500 µA max per amplifier - allows dual-channel operation in battery-powered portable equipment |
| Input Offset Voltage | 2.5 mV max (full temp range) - provides adequate DC accuracy for non-critical precision applications |

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), lower input offset (1.5 mV max), but higher supply current (650 µA max) | Better suited for higher-speed multiplexed sensor arrays requiring faster settling | Select TLV2432IDR when bandwidth >1 MHz and settling time <3 µs are required |
| OPA2333AIDR | Zero-drift architecture, 2 µV max offset, 0.65 µV/°C drift, but 17 µA supply current per channel | Targeted at ultra-precision DC-coupled systems where long-term stability dominates power budget | Select OPA2333AIDR only when sub-10 µV offset stability over temperature and time is mandatory |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262QDG4 offers the optimal balance of rail-to-rail output, ultra-low input bias current, and automotive-grade temperature range at moderate power consumption - making it ideal for cost-sensitive, high-reliability sensor signal chains where precision is important but not extreme.

FAQ
What is the operating temperature range for the TLC2262QDG4?
The TLC2262QDG4 is qualified for operation from –40°C to 125°C, meeting Q-temp automotive requirements. This rating is confirmed in the device's ordering information table and absolute maximum ratings section, where the "Q" suffix explicitly denotes the –40°C to 125°C grade. The SOIC-8 (D) package supports this full range without derating under recommended operating conditions.
Does the TLC2262QDG4 support single-supply operation?
Yes, the TLC2262QDG4 fully supports single-supply operation. Its common-mode input voltage range includes the negative rail (GND), and its rail-to-rail output swings from within 10 mV of GND to within 10 mV of VDD. When powered from 0 V and +5 V, it delivers usable output from ~0.01 V to ~4.99 V at 25°C - verified in the electrical characteristics tables for VDD = 5 V configuration.
What is the input offset voltage specification for the TLC2262QDG4?
The TLC2262QDG4 has a maximum input offset voltage of 2.5 mV over the full operating temperature range (–40°C to 125°C). At 25°C, the typical value is 300 µV and maximum is 2500 µV. This specification is documented in the "TLC2262I electrical characteristics" table, which applies to all "Q" and "I" suffix variants sharing the same performance binning.
Is the TLC2262QDG4 pin-compatible with other TLC2262 variants?
Yes, the TLC2262QDG4 is pin-compatible with all SOIC-8 packaged TLC2262 variants including TLC2262CD, TLC2262ID, and TLC2262AQD. The pinout is standardized across the D-package family as shown in the "D, P, OR PW PACKAGE (TOP VIEW)" diagram - confirming identical terminal assignments for all eight pins regardless of temperature grade or offset voltage bin.
What packaging and compliance information applies to the TLC2262QDG4?
The TLC2262QDG4 is supplied in an 8-pin SOIC (D) package, RoHS-compliant, with lead finish NiPdAu. The "G4" suffix indicates tape-and-reel packaging per JEDEC standard J-STD-020, and the device meets TI's green chemistry requirements. Moisture sensitivity level (MSL) is Level 2a per J-STD-020, with floor life of 1 year at ≤30°C/60% RH.
