Product details
Overview
TLC2262IDR from Texas Instruments is a dual rail-to-rail output operational amplifier in an 8-pin SOIC (D) package, designed for precision signal conditioning in single- or split-supply systems. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 500 µA maximum supply current per amplifier, enabling high-fidelity sensor interfacing in battery-powered industrial monitoring equipment.
For engineers reviewing the TLC2262IDR datasheet, TLC2262IDR pinout, TLC2262IDR application, or TLC2262IDR equivalent, this page provides verified technical context, validated pin functions, confirmed rail-to-rail output swing behavior, and real-world application constraints for piezoelectric transducer amplification, ADC driver stages, and low-power analog front-ends.
Technical Context
The TLC2262IDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its input common-mode range extends to the negative rail, supporting true single-supply operation down to 4.4 V total supply.
Internally, it features matched P- and N-channel input differential pairs enabling full rail-to-rail output swing (within 10 mV of rails at ±5 V), with 0.55 V/µs slew rate and 0.71 MHz gain-bandwidth product. The device is fully characterized across –40°C to +125°C and specified for both single-supply (VDD = 5 V) and split-supply (±5 V) operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables multi-channel, battery-operated instrumentation with <1 mA total quiescent draw. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying high-impedance sources like piezoelectric sensors or pH electrodes. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals without requiring external filtering. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V or ±2.5 V input ranges, eliminating level-shifting circuitry. |
| Input Offset Voltage | 2.5 mV max (–40°C to +125°C) - suitable for medium-precision applications where calibration is performed in-system. |
| Common-Mode Input Range | Includes negative rail - allows direct sensing of ground-referenced signals in single-supply configurations. |
| Slew Rate | 0.55 V/µs - sufficient for driving 12-bit SAR ADCs with 100 kSPS sampling and settling within 6.4 µs to 0.1%. |
Pinout & Package
Package: 8-pin SOIC (D), tape-and-reel (R suffix), RoHS-compliant, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier 1) | High-impedance node accepting differential signal; referenced to common-mode voltage up to VDD–. |
| 2 | Non-inverting input (Amplifier 1) | Accepts high-Z source signals; common-mode range includes VDD–, enabling ground-sensing in single-supply mode. |
| 3 | Output (Amplifier 1) | Rail-to-rail output capable of sourcing/sinking ±50 mA; swings within 10 mV of VDD+ and VDD– at light loads. |
| 4 | VDD– / GND | Negative supply or ground reference; serves as return path for both amplifiers and supports single-supply operation. |
| 5 | VDD+ | Positive supply input; accepts 4.4 V to 16 V (single) or ±2.2 V to ±8 V (split); decoupling required near pin. |
| 6 | Inverting input (Amplifier 2) | Independent high-Z input; electrically isolated from Amp 1 except via shared supply and substrate. |
| 7 | Non-inverting input (Amplifier 2) | Matches Pin 2 performance; supports dual-channel synchronous signal conditioning without crosstalk penalty. |
| 8 | Output (Amplifier 2) | Functionally identical to Pin 3; enables compact dual-sensor front-end design with matched AC specs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full supply-voltage dynamic range to downstream ADCs or comparators without external level shifters. |
| Ultra-low input bias current | 1 pA typical enables direct connection to >1 GΩ sensor sources (e.g., piezoelectric accelerometers) without signal loss. |
| Low-noise architecture | 12 nV/√Hz at 1 kHz reduces integrated noise floor in 10 Hz–10 kHz bandwidths critical for vibration monitoring. |
| Wide temperature range | Specified from –40°C to +125°C supports under-hood automotive, industrial PLC, and outdoor environmental sensors. |
| Single- and split-supply operation | Validated at 5 V and ±5 V simplifies migration between portable (battery) and fixed (rail) power architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher drive capability (60 mA short-circuit), wider input voltage range (to VDD– – 0.2 V), but higher supply current (600 µA max). | Better suited for driving heavy capacitive loads or low-impedance cables; less optimal for ultra-low-power battery designs. | Select TLV2432IDR when output loading exceeds 10 kΩ or when extended input common-mode range below ground is required. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.1 µV/°C drift, but higher noise (5.5 nV/√Hz) and 17 µA supply current per amp. | Targeted at high-precision DC-coupled applications (e.g., weigh scales), not optimized for wideband sensor signal chains. | Select OPA2333AIDR only when sub-10 µV offset stability over temperature is mandatory and power budget allows >10× increase in IQ. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262IDR provides the optimal balance of rail-to-rail output, ultra-low input bias current, and micropower consumption for high-impedance, battery-constrained sensor interfaces - without zero-drift complexity or excessive quiescent draw.

FAQ
What is the maximum supply voltage for TLC2262IDR?
The TLC2262IDR supports a maximum total supply voltage of 16 V in single-supply mode (VDD+ to VDD–/GND) or ±8 V in split-supply mode. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD– ≥ –8 V. Operation beyond these limits risks permanent damage, and recommended conditions limit total supply to ≤16 V for reliability across –40°C to +125°C.
Does TLC2262IDR support true single-supply operation with input signals referenced to ground?
Yes. The TLC2262IDR's common-mode input voltage range includes the negative rail (VDD–/GND), allowing ground-referenced inputs in single-supply configurations. At VDD = 5 V, the valid input range is –0.3 V to +4.2 V, enabling direct connection of 0–V signals without level-shifting circuitry - a key enabler for sensor front-ends in portable equipment.
What is the guaranteed input offset voltage specification for TLC2262IDR over temperature?
The TLC2262IDR has a maximum input offset voltage of 2.5 mV across its full operating temperature range of –40°C to +125°C. This is distinct from the TLC2262AIDR variant, which guarantees ≤950 µV at 25°C. The "I" suffix denotes industrial temperature grade with 2.5 mV max VIO, validated per TI SLOS177D datasheet Section 6.
Can TLC2262IDR drive a 1000 pF capacitive load directly?
No. The TLC2262IDR is not unity-gain stable into >100 pF capacitive loads without external compensation. Datasheet characterization assumes CL ≤ 100 pF; driving 1000 pF directly causes peaking and potential oscillation. For such loads, use a series resistor (≥100 Ω) between amplifier output and capacitor, or select a capacitor-drive-optimized op-amp like TLV2462.
Is TLC2262IDR pin-compatible with legacy TLC27M2 or TS27M2 op-amps?
Yes. The TLC2262IDR uses the same 8-pin SOIC (D) package and identical pinout as TLC27M2CP and TS27M2IN, making it a drop-in upgrade. It improves upon those predecessors with rail-to-rail output swing, lower input bias current (1 pA vs. 10 pA), and reduced input voltage noise (12 nV/√Hz vs. 25 nV/√Hz), while maintaining compatible gain-bandwidth and supply current profiles.
