Product details
Overview
TLC2262AIDR from Texas Instruments is a dual rail-to-rail output operational amplifier in SOIC-8 package, designed for precision signal conditioning in single- or split-supply systems. It delivers 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and full rail-to-rail output swing - enabling direct interfacing with 5-V or ±5-V ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2262AIDR datasheet, TLC2262AIDR pinout, TLC2262AIDR application, or TLC2262AIDR equivalent, key selection criteria include its guaranteed low VIO (≤950 µV), ultra-low input bias current (1 pA typ), common-mode input range extending to the negative rail, and operation across –40°C to 125°C industrial temperature range - critical for high-impedance transducer amplification and portable instrumentation.
Technical Context
The TLC2262AIDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current and low noise. Its input stage supports common-mode voltages down to VDD–, and its output drives within 100 mV of both rails under 1 mA load at 5 V supply.
It operates over ±2.2 V to ±8 V dual supply or 4.4 V to 16 V single supply, with specified performance at 5 V and ±5 V. The device exhibits 0.55 V/µs typical slew rate, 0.71 MHz gain-bandwidth product, and 56° phase margin - optimized for stable unity-gain and closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 950 µV max at 25°C - enables DC-coupled precision amplification without trimming in 12-bit+ systems |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying from >1 GΩ sources (e.g., piezoelectric sensors) |
| Supply Current | 500 µA max per amplifier - supports multi-channel, low-power operation in handheld and remote monitoring devices |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V or ±2.5 V input ranges, minimizing headroom loss |
| Input Noise Voltage | 12 nV/√Hz at 1 kHz - 3× lower than prior-generation TLC27M2, improving SNR in audio and sensor signal chains |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows ground-referenced single-supply designs without level-shifting circuitry |
| Operating Temperature | –40°C to +125°C - qualified for industrial and automotive under-hood applications requiring extended thermal stability |

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), wider GBW (2.2 MHz), but higher supply current (600 µA typ) and 1.5 mV max VIO | Better for AC-coupled audio or fast-settling data acquisition; less suitable for ultra-low-drift DC sensing | Choose TLV2432IDR when bandwidth >1 MHz and faster settling are required; accept higher power and reduced DC precision |
| OPA2333AIDR | Zero-drift architecture, 10 µV max VIO, 0.17 µV/°C drift, but higher noise (57 nV/√Hz) and 17 µA supply current | Superior for microvolt-level DC measurements (e.g., thermopile amplification); not optimal for wideband sensor signals | Choose OPA2333AIDR only when sub-20 µV offset and near-zero drift dominate requirements; avoid where noise or speed matters |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262AIDR provides the best balance of low offset (950 µV), ultra-low bias current (1 pA), and moderate power (500 µA) for high-impedance, battery-operated precision analog front-ends - making it uniquely suited for piezoelectric, strain, and medical sensor interfaces where DC accuracy and source loading are critical.

FAQ
What is the maximum operating supply voltage for the TLC2262AIDR?
The TLC2262AIDR supports absolute maximum supply voltages of +8 V on VDD+ and –8 V on VDD–. For reliable operation, the recommended range is ±2.2 V to ±8 V dual supply or 4.4 V to 16 V single supply. Exceeding these limits risks permanent damage, and operation above ±8 V violates the Absolute Maximum Ratings table in the SLOS177D datasheet.
Does the TLC2262AIDR support true rail-to-rail input?
No, the TLC2262AIDR features rail-to-rail *output* only. Its common-mode input voltage range extends to the negative rail (VDD–) but stops 1.5 V below the positive rail (VDD+ – 1.5 V) under recommended conditions. This allows ground-referenced single-supply use but requires input signals to remain within that limited upper bound.
How does the TLC2262AIDR differ from the standard TLC2262IDR?
The TLC2262AIDR belongs to the "A" grade variant, specifying 950 µV max input offset voltage at 25°C, whereas the TLC2262IDR (non-A) has 2.5 mV max VIO. Both share identical pinout, package (SOIC-8), temperature range (–40°C to +125°C), and all other electrical characteristics - the "A" suffix denotes tighter DC precision for applications demanding lower initial error.
Can the TLC2262AIDR drive capacitive loads directly?
The TLC2262AIDR is stable with up to 100 pF capacitive load when driving into 50 kΩ, as verified by 56° phase margin in the datasheet. For larger loads (>100 pF), external isolation resistance (e.g., 10–50 Ω in series with the output) is required to prevent peaking or oscillation - especially critical in ADC driver and filter applications.
Is the TLC2262AIDR suitable for automotive applications?
Yes - the "I" temperature suffix (–40°C to +125°C) and Q-Temp qualification path make the TLC2262AIDR appropriate for non-safety-critical automotive applications such as cabin temperature sensing, seat position detection, and HVAC control. It meets AEC-Q100 stress testing requirements for Grade 2 (105°C ambient) when used within its specified operating conditions.
