Product details
Overview
TLC2262IP from Texas Instruments is a dual rail-to-rail output operational amplifier in an 8-pin plastic DIP package, designed for precision signal conditioning in single- or split-supply systems. It delivers 12 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current, and rail-to-rail output swing - enabling direct interfacing with 5 V ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2262IP datasheet, TLC2262IP pinout, TLC2262IP application, or TLC2262IP equivalent, key selection criteria include its guaranteed 950 µV max input offset voltage (TLC2262A grade), –40°C to 125°C operating range, low-noise performance at micropower levels, and compatibility with high-impedance piezoelectric transducers and remote analog sensing nodes.
Technical Context
The TLC2262IP 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 stage operates down to the negative rail, supporting true single-supply operation with common-mode input range extending from VDD– to VDD+ – 1.5 V.
It features a unity-gain stable architecture with 0.55 V/µs slew rate, 0.71 MHz gain-bandwidth product, and 56° phase margin under 50 kΩ//100 pF load conditions - optimized for stability in low-power, medium-bandwidth instrumentation and data acquisition circuits without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables multi-channel, battery-operated systems with >1-year runtime on coin cells. |
| Input Offset Voltage | 950 µV max at 25°C (TLC2262A grade) - supports 12-bit accuracy without trimming in DC-coupled sensor interfaces. |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying from >1 GΩ sources like piezoelectric sensors or pH electrodes. |
| Output Swing | Rail-to-rail (within 10 mV of rails at 100 µA load) - maximizes dynamic range into 5 V SAR ADCs without level-shifting circuitry. |
| Input Noise Density | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLC27M2, critical for low-amplitude biopotential or strain gauge signals. |
| Common-Mode Range | Includes negative rail (VDD–) - allows direct sensing of ground-referenced signals in single-supply configurations. |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood and industrial control applications per AEC-Q100 stress testing. |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, JEDEC MS-001 compatible, lead temperature rated to 260°C for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA; rail-to-rail swing supports full 0–5 V ADC input range. |
| 2 | IN1– | Inverting input - high-impedance node (10¹² Ω); connects to feedback network or differential reference. |
| 3 | IN1+ | Non-inverting input - accepts signals from high-Z sources; common-mode range includes VDD– (ground in single-supply). |
| 4 | GND / VDD– | Power return / negative supply - serves as reference for both inputs and output; no separate ground pin required. |
| 5 | IN2+ | Non-inverting input (amp 2) - independent channel for dual-sensor readout or signal buffering. |
| 6 | IN2– | Inverting input (amp 2) - supports differential configuration or active filtering with independent gain setting. |
| 7 | OUT2 | Amplifier 2 output - electrically isolated from OUT1; enables dual-channel signal conditioning on one IC. |
| 8 | VDD+ | Positive supply - operates from ±2.2 V to ±8 V or single 4.4 V to 16 V; internal ESD protection rated per JEDEC JS-001. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full supply voltage swing (e.g., 0–5 V on 5 V single supply), eliminating need for level-shifting before ADC input. |
| Low input bias current | 1 pA typical enables accurate amplification of nanoamp-level currents from photodiodes or electrochemical sensors. |
| Low-noise architecture | 12 nV/√Hz at 1 kHz reduces integrated noise in 10 Hz–10 kHz bandwidths, improving SNR in audio and vibration sensing. |
| Single- and split-supply support | Fully specified from 4.4 V single supply to ±8 V dual supply - simplifies design reuse across portable and industrial platforms. |

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 |
|---|---|---|---|
| TLV2432IP | Higher output drive (±30 mA vs ±50 mA), wider input voltage range (to VDD– + 0.1 V), but higher supply current (1.4 mA vs 0.5 mA). | Better suited for driving heavier capacitive loads or DAC buffers; less optimal for ultra-low-power sensor nodes. | Select TLV2432IP when output current >20 mA or AC performance (SR = 1.5 V/µs) is prioritized over quiescent power. |
| TLC2272IP | Higher slew rate (1.7 V/µs), greater GBW (2.2 MHz), but higher noise (25 nV/√Hz) and input bias current (10 pA). | Preferred for audio line drivers or active filters requiring bandwidth >1 MHz; trades off precision and power efficiency. | Choose TLC2272IP only when system bandwidth exceeds 500 kHz and noise budget allows ≥2× increase over TLC2262IP. |
Compared with TLV2432IP and TLC2272IP, the TLC2262IP uniquely balances micropower consumption (500 µA), precision (950 µV VIO), and low noise (12 nV/√Hz) - making it the optimal choice for battery-constrained, high-accuracy analog front-ends where bandwidth ≤1 MHz suffices.

FAQ
What is the maximum supply voltage rating for the TLC2262IP?
The TLC2262IP has an absolute maximum supply voltage rating of ±8 V for split-supply operation or 16 V for single-supply use. Operation beyond these limits risks permanent damage. Recommended operating range is ±2.2 V to ±8 V (split) or 4.4 V to 16 V (single), with full electrical specifications guaranteed across this span for the TLC2262IP variant.
Does the TLC2262IP support true single-supply operation with input signals referenced to ground?
Yes, the TLC2262IP supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–), which is typically ground in single-supply configurations. This allows ground-referenced sensor signals (e.g., from thermistors or RTDs) to be applied directly to IN+ or IN– without level-shifting circuitry, simplifying front-end design.
How does the TLC2262IP differ from the standard TLC2262CP in terms of performance and qualification?
The TLC2262IP is the industrial-grade version (–40°C to +125°C) with tighter input offset voltage specification (950 µV max vs 2500 µV max for TLC2262CP) and AEC-Q100-aligned stress qualification. Both share identical pinout and basic electrical parameters, but the 'I' suffix denotes extended temperature validation and enhanced long-term stability - critical for automotive and harsh-environment deployments where the TLC2262CP is not rated.
Can the TLC2262IP drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC2262IP maintains rail-to-rail output swing into 10 kΩ loads: at 100 µA load current, output reaches within 10 mV of both rails (e.g., 0.01 V and 4.99 V on 5 V supply). Its ±50 mA short-circuit output current capability ensures robustness even under transient overload, and closed-loop output impedance remains below 240 Ω at 100 kHz - preserving gain accuracy in precision buffer applications.
Is a compensation capacitor required when using the TLC2262IP in unity-gain follower configuration?
No external compensation capacitor is required for unity-gain stability. The TLC2262IP is internally compensated and exhibits 56° phase margin with 50 kΩ load and 100 pF capacitive load - meeting standard unity-gain stability criteria. Layout best practices (short traces, local bypass capacitors) are sufficient; adding external compensation degrades bandwidth and increases noise without benefit.
