Product details
Overview
TLC2262AMUB from Texas Instruments is a dual rail-to-rail output operational amplifier in ceramic DIP (JG) package, rated for –55°C to 125°C operation with max input offset voltage of 950 µV at 25°C. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and supports single- or split-supply operation up to ±8 V. It is used in precision signal conditioning for high-impedance piezoelectric transducers and battery-powered remote sensing.
For engineers reviewing the TLC2262AMUB datasheet, TLC2262AMUB pinout, TLC2262AMUB application, or TLC2262AMUB equivalent, key selection criteria include its rail-to-rail output swing, ultra-low 1 pA typical input bias current, guaranteed 950 µV VIO max over temperature, and qualification for high-reliability automotive environments.
Technical Context
The TLC2262AMUB employs 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 at 1 kHz). Its common-mode input range extends to the negative rail, enabling true single-supply operation with ground-referenced inputs.
It features fully specified performance across –55°C to 125°C, including 500 µA max supply current per amplifier, 0.55 V/µs typical slew rate, and 710 kHz gain-bandwidth product. The device is characterized at both 5 V single-supply and ±5 V split-supply conditions, with CMRR ≥75 dB and PSRR ≥80 dB.

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 supply current (650 µA typ), lower VIO (1.5 mV max), SOIC-8 package | Optimized for higher-speed, lower-precision applications; not qualified for –55°C operation | Select TLV2432IDR only if speed (1.5 MHz GBW) outweighs temperature range and power constraints. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 17 µA supply current, but limited output drive (±25 mA) | Superior DC precision and drift performance, but insufficient output current for driving capacitive loads or low-Z filters | Choose OPA2333AIDR only when sub-µV offset stability is mandatory and load requirements are ≤10 kΩ. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262AMUB uniquely balances ultra-low bias current, rail-to-rail output, extended temperature range, and hermetic ceramic packaging-making it irreplaceable in high-reliability, high-impedance, wide-temperature analog signal chains where long-term stability and noise performance are co-critical.

FAQ
What is the maximum operating temperature range for the TLC2262AMUB?
The TLC2262AMUB is rated for continuous operation from –55°C to 125°C. This extended range is validated per MIL-PRF-38535 requirements and supports deployment in under-hood automotive, avionics, and industrial control environments where thermal extremes are routine. The "M" suffix explicitly denotes this military-grade temperature qualification.
Does the TLC2262AMUB support single-supply operation?
Yes, the TLC2262AMUB fully supports single-supply operation. Its common-mode input voltage range includes the negative rail (VDD–/GND), and its rail-to-rail output swings within ~10 mV of both supply rails. When operated from a 5 V single supply, it accepts inputs from 0 V to 3.5 V and delivers outputs from 0.01 V to 4.99 V (at 25°C, IO = 50 µA), enabling direct interfacing with unipolar ADCs and microcontrollers.
What is the input offset voltage specification for the TLC2262AMUB?
The TLC2262AMUB has a maximum input offset voltage of 950 µV at 25°C, and 1500 µV over its full –55°C to 125°C operating range. This value applies specifically to the "A" grade variant (TLC2262A), which distinguishes it from the standard TLC2262 (2.5 mV max). The "MUB" suffix confirms the ceramic JG package and military temperature grade.
How does the TLC2262AMUB compare to the TLC2262CP in terms of performance and reliability?
The TLC2262AMUB and TLC2262CP share identical electrical specifications (e.g., 950 µV VIO max, 1 pA IIB, rail-to-rail output), but differ critically in package and qualification. The TLC2262AMUB uses a hermetic ceramic DIP (JG) package rated for –55°C to 125°C and compliant with MIL-PRF-38535, whereas the TLC2262CP uses a plastic DIP (P) package rated only for 0°C to 70°C. This makes the TLC2262AMUB suitable for high-reliability, mission-critical applications where moisture resistance and thermal cycling endurance are essential.
Is the TLC2262AMUB pin-compatible with other devices in the TLC226x family?
Yes, the TLC2262AMUB is pin-compatible with all 8-pin TLC2262 variants-including TLC2262CD, TLC2262CP, TLC2262AIP, and TLC2262ID-in the same JG, D, P, or PW packages. Pin functions (OUT1, IN1–, IN1+, VDD–/GND, VDD+, OUT2, IN2–, IN2+) are identical across the family. However, electrical performance (e.g., VIO, temperature range) and package robustness vary by suffix, so system-level validation remains necessary for drop-in replacement.
