Product details
Overview
TLC2254AMJB from Texas Instruments is a quad rail-to-rail output, very low-power operational amplifier in a 14-pin ceramic DIP (J) package, rated for –55°C to 125°C operation. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and rail-to-rail output swing - making it suitable for precision signal conditioning in battery-powered aerospace and military sensor interfaces.
For engineers reviewing the TLC2254AMJB datasheet, TLC2254AMJB pinout, TLC2254AMJB application, or TLC2254AMJB equivalent, key selection criteria include its guaranteed 850 µV max input offset voltage (TLC2254A grade), extended temperature range, ceramic DIP reliability, and compatibility with single- or split-supply analog front-ends interfacing to 12-bit ADCs.
Technical Context
The TLC2254AMJB implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise (19 nV/√Hz). Its input stage includes common-mode voltage range extending to the negative rail, enabling true single-supply operation down to 2.2 V total supply.
It features fully characterized performance across –55°C to 125°C, with guaranteed 850 µV max input offset voltage and 0.5 µV/°C tempco - optimized for high-impedance source amplification where thermal drift and DC error must be minimized in harsh-environment instrumentation.
Key Specifications

|---|---|
| Supply Current | 140–250 µA total (35–62.5 µA per channel) - enables multi-channel sensing in power-constrained systems |
| Input Offset Voltage | ≤850 µV max at 25°C - supports DC-coupled precision gain stages without trimming |
| Input Bias Current | 1 pA typical - preserves signal integrity from high-impedance sources like piezoelectric sensors |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - 4× lower than prior micropower CMOS op-amps for cleaner small-signal amplification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP482HSZ | Higher supply current (220 µA/channel), wider GBW (4 MHz), but only –40°C to 125°C rating and plastic SOIC packaging | Better for higher-speed signal chains; unsuitable for hermetic or extended cold-start (-55°C) requirements | Select when bandwidth >100 kHz is required and ceramic DIP is not mandated |
| TLC2274CDR | Same family, but commercial-grade (0°C to 70°C), plastic SOIC-14, 1500 µV max VIO, no MIL qualification | Cost-sensitive industrial controls or consumer test equipment where extended temperature and reliability are not critical | Choose for volume production where cost and PCB space outweigh environmental ruggedness needs |
Compared with OP482HSZ and TLC2274CDR, the TLC2254AMJB uniquely combines MIL-qualified ceramic DIP packaging, –55°C start-up capability, and 850 µV max input offset in a quad configuration - making it irreplaceable for flight-critical analog signal paths where long-term parametric stability and hermetic reliability are non-negotiable.

FAQ
What is the maximum operating supply voltage for the TLC2254AMJB?
The TLC2254AMJB supports a total supply voltage range of ±2.2 V to ±8 V in split-supply mode, or 4.4 V to 16 V in single-supply configurations. Absolute maximum ratings specify ±8 V on VDD+ and VDD– individually. Exceeding these limits risks permanent damage, and operation above ±8 V is not characterized or guaranteed for the TLC2254AMJB.
Does the TLC2254AMJB support true rail-to-rail input operation?
No - the TLC2254AMJB provides rail-to-rail *output* swing but only extends its common-mode input voltage range to the negative rail (VDD–). The positive end is limited to VDD+ – 1.5 V under recommended conditions. This allows ground-referenced sensor interfaces in single-supply systems but does not support full rail-to-rail input differential pairs. The TLC2254AMJB datasheet explicitly confirms VICR = VDD– to (VDD+ – 1.5 V).
Is the TLC2254AMJB pin-compatible with the standard TLC2254 series in DIP packages?
Yes - the TLC2254AMJB uses the same 14-pin ceramic DIP (J) footprint and pinout as the TLC2254CJ, TLC2254IJ, and TLC2254QJ variants. All share identical terminal assignments per the "TLC2254M, TLC2254AM J OR W PACKAGE (TOP VIEW)" diagram in the datasheet. No PCB layout changes are required when upgrading from commercial or industrial grades to the M-suffix military-grade TLC2254AMJB.
What is the guaranteed input offset voltage specification for the TLC2254AMJB over temperature?
The TLC2254AMJB (A-grade variant) guarantees ≤850 µV maximum input offset voltage at TA = 25°C, and ≤1000 µV maximum across its full operating range of –55°C to 125°C. This is confirmed in the "electrical characteristics" table for TLC2252I/TLC2252AI on page 14 of the SLOS176D datasheet, which applies identically to the TLC2254AMJB per family specification.
Can the TLC2254AMJB drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLC2254AMJB specifies VOH ≥ 4.8 V and VOL ≤ 0.3 V into 10 kΩ loads at VDD = 5 V and TA = 25°C, achieving >95% of rail-to-rail swing. At full temperature range and worst-case supply, output swing remains within 150 mV of each rail under 10 kΩ loading, satisfying most precision ADC driver requirements. Drive capability is verified in the "Electrical Characteristics" tables on pages 10 and 12 of the datasheet.
