Product details
Overview
TLC2262CPWRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier in TSSOP-8 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 low-noise, micropower operation in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLC2262CPWRG4 datasheet, TLC2262CPWRG4 pinout, TLC2262CPWRG4 application, or TLC2262CPWRG4 equivalent, this device is selected for high-impedance source amplification, rail-to-rail output swing into ADC inputs, low-offset analog front-ends, and space-constrained industrial monitoring designs requiring stable CMOS op-amp performance across 0°C to 70°C.
Technical Context
The TLC2262CPWRG4 uses 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, supporting true single-supply operation down to 4.4 V total supply.
It features fully specified performance at both 5 V single-supply and ±5 V split-supply configurations, with 0.55 V/µs slew rate, 0.71 MHz gain-bandwidth product, and 70 dB minimum CMRR - optimized for DC-coupled precision amplification without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables multi-channel, battery-operated instrumentation with minimal quiescent power 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 signal conditioning for sub-mV-level sensor outputs. |
| Rail-to-Rail Output | Swing within 10 mV of both rails at 100 µA load - maximizes dynamic range when driving SAR or delta-sigma ADCs directly. |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows direct interfacing with ground-referenced transducers in single-supply systems. |
| Input Offset Voltage | 2500 µV max at 25°C - suitable for moderate-precision applications where trimming is not required. |
| Gain-Bandwidth Product | 0.71 MHz - sufficient for anti-aliasing filters, sensor amplification, and medium-speed closed-loop control loops. |
Pinout & Package
TLC2262CPWRG4 is housed in an 8-pin TSSOP (PW) package with 0.65 mm pitch, surface-mount footprint, and exposed pad for thermal enhancement. Pin numbering follows standard JEDEC TSSOP-8 orientation (pin 1 marked).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing supports full-scale ADC input utilization. |
| 2 | IN– A | Inverting input of Amplifier A - high-impedance node (10¹² Ω) minimizes loading on feedback networks and sensors. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts common-mode voltages from VDD– to VDD+ – 1.5 V. |
| 4 | GND / VDD– | Negative supply or ground reference - serves as return path for both amplifiers; common to all channels. |
| 5 | VDD+ | Positive supply input - operates from 4.4 V to 16 V single supply or ±2.2 V to ±8 V split supply. |
| 6 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; identical input characteristics. |
| 7 | IN– B | Inverting input of Amplifier B - supports independent feedback configuration per channel. |
| 8 | OUT B | Amplifier B output - fully independent output stage; no crosstalk observed in typical operating conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into ADCs without level-shifting circuitry, reducing component count and board area. |
| Low input bias current (1 pA) | Enables use with ultra-high-impedance sources (e.g., glass pH electrodes, photodiode transimpedance stages) without significant offset error. |
| Low noise (12 nV/√Hz) | Improves signal-to-noise ratio in precision measurement paths, especially critical for 16-bit+ data acquisition systems. |
| Single- and split-supply operation | Eliminates need for separate design variants - same schematic works for 5 V microcontroller systems and ±5 V test equipment. |
| Stable at unity gain | Guaranteed phase margin ≥56° with 100 pF capacitive load - simplifies layout and avoids external compensation in most configurations. |

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), lower input offset (1.5 mV max), but higher supply current (600 µA max). | Better for higher-speed closed-loop control; less suitable for ultra-low-power battery operation. | Select TLV2432IDR when bandwidth >1 MHz or offset <1.5 mV is required; avoid if quiescent current budget is <500 µA. |
| TLC2272CPW | Improved AC performance (2 MHz GBW, 3.6 V/µs SR), but higher noise (25 nV/√Hz) and supply current (1.3 mA max). | Targeted at audio and active filter applications; not optimized for low-noise sensor front-ends. | Choose TLC2272CPW for higher-frequency signal paths where noise is secondary; retain TLC2262CPWRG4 for precision, low-power sensing. |
Compared with TLV2432IDR and TLC2272CPW, the TLC2262CPWRG4 provides the optimal balance of micropower operation (500 µA), low noise (12 nV/√Hz), and rail-to-rail output - making it uniquely suited for battery-powered, high-impedance sensor interfaces where power, noise, and dynamic range are simultaneously constrained.

FAQ
What is the operating temperature range for the TLC2262CPWRG4?
The TLC2262CPWRG4 is rated for 0°C to 70°C free-air operating temperature (C-suffix grade), making it suitable for commercial and industrial indoor applications. It is not qualified for extended temperature ranges like automotive (–40°C to 125°C) or military grades - those require TLC2262I or TLC2262Q variants.
Does the TLC2262CPWRG4 support single-supply operation?
Yes, the TLC2262CPWRG4 is fully specified for single-supply operation from 4.4 V to 16 V. Its common-mode input range includes the negative rail (GND), and its rail-to-rail output swings within 10 mV of both supply rails - enabling direct interface with microcontroller ADCs without level-shifting circuitry.
What is the maximum input offset voltage of the TLC2262CPWRG4?
The TLC2262CPWRG4 has a maximum input offset voltage of 2500 µV at 25°C and 3000 µV across the full 0°C to 70°C operating range. This distinguishes it from the 'A' variant (TLC2262ACPWRG4), which guarantees ≤950 µV max at 25°C for higher-precision applications.
Can the TLC2262CPWRG4 drive capacitive loads directly?
The TLC2262CPWRG4 is stable with up to 100 pF capacitive load at unity gain (phase margin ≥56°), as verified in the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain stability and prevent peaking or oscillation.
Is the TLC2262CPWRG4 pin-compatible with older TI op-amps like the TLC27M2?
Yes, the TLC2262CPWRG4 shares the same TSSOP-8 pinout as the TLC27M2CPW and TS27M2CPW, enabling drop-in replacement in existing designs. It improves upon them with rail-to-rail output, lower noise (12 vs. 25 nV/√Hz), lower input offset, and lower input bias current - enhancing performance without layout changes.
