Product details
Overview
TLC2262CPW 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 0.55 V/µs slew rate, 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current per amplifier, and supports ±2.2 V to ±8 V operation - ideal for interfacing with low-voltage ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2262CPW datasheet, TLC2262CPW pinout, TLC2262CPW application, or TLC2262CPW equivalent, key selection criteria include its rail-to-rail output swing, ultra-low input bias current for high-impedance source buffering, low-noise performance in sub-1 MHz bandwidth applications, and compatibility with 5 V or ±5 V supplies without level-shifting circuitry.
Technical Context
The TLC2262CPW uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (10¹² Ω) and micropower operation. Its input stage includes common-mode input voltage range extending to the negative rail, enabling true single-supply operation down to 0 V ground reference.
Internally, it features matched P-channel and N-channel input transistors for low offset drift (2 µV/°C), integrated ESD protection, and stable unity-gain compensation (56° phase margin). The device is fully characterized across 0°C to 70°C and specified for both single-supply (VDD = 5 V) and split-supply (±5 V) configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V or 4.4 V to 16 V - supports wide industrial and portable supply rails without external regulators. |
| Input Bias Current | 1 pA typ - enables accurate amplification of signals from piezoelectric sensors, pH electrodes, and other high-impedance sources. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLC27M2, critical for low-level analog signal integrity. |
| Slew Rate | 0.55 V/µs typ - sufficient for 100 kHz full-power bandwidth with 2 Vpp output, suitable for data acquisition and active filtering. |
| Output Swing | Rail-to-rail - delivers >99% of supply voltage range (e.g., 0.01 V to 4.99 V on 5 V supply), maximizing dynamic range into ADCs. |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows direct sensing of signals referenced to ground in single-supply systems. |
| Supply Current | 500 µA max per amplifier - enables dual-opamp operation in sub-1 mA total system power budgets. |
Pinout & Package
TSSOP-8 (PW) package: 4.4 mm × 3.0 mm, 0.65 mm pitch, thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing enables direct interface to SAR ADC reference inputs. |
| 2 | IN– A | Inverting input of Amp A - high-impedance node (10¹² Ω); sensitive to PCB leakage; requires guard ring in high-Z designs. |
| 3 | IN+ A | Non-inverting input of Amp A - same impedance as IN–; used for unity-gain buffer or differential sensing configurations. |
| 4 | GND / VDD– | Ground or negative supply - shared return path; must be low-impedance to avoid PSRR degradation and crosstalk. |
| 5 | VDD+ | Positive supply - accepts 4.4–16 V (single) or ±2.2–±8 V (split); decoupling capacitor required within 1 cm. |
| 6 | IN+ B | Non-inverting input of Amp B - independent channel; enables dual-sensor conditioning or signal + reference paths. |
| 7 | IN– B | Inverting input of Amp B - matched to Amp A for common-mode rejection in differential configurations. |
| 8 | OUT B | Amplifier B output - identical specs to OUT A; supports independent gain stages or dual-channel signal chains. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers 0.01 V to 4.99 V swing on 5 V supply - eliminates need for level-shifting when driving 12-bit+ ADCs. |
| Ultra-low input bias current | 1 pA typical - reduces voltage error below 1 mV even with 10 MΩ source impedance, critical for electrochemical sensors. |
| Low input voltage noise | 12 nV/√Hz at 1 kHz - improves SNR by >10 dB vs. bipolar op-amps in audio and instrumentation front-ends. |
| Single- and split-supply support | Fully specified at 5 V and ±5 V - simplifies design reuse across portable (3.3/5 V) and industrial (±15 V) platforms. |
| High CMRR & PSRR | 83 dB CMRR and 95 dB PSRR - rejects power supply ripple and common-mode interference in noisy environments. |

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), higher supply current (1.3 mA), wider GBW (2.3 MHz) | Better for higher-frequency active filters or fast-settling multiplexed data acquisition | Select TLV2432IDR when bandwidth >1 MHz or settling time <1 µs is required; not drop-in due to different quiescent current and layout thermal profile. |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, 60 nVpp 0.1–10 Hz noise, 17 µA supply current | Superior DC precision for long-term sensor calibration; lower power but narrower bandwidth (350 kHz) | Choose OPA2333AIDR for ultra-stable offset in temperature-compensated strain gauge bridges; TLC2262CPW preferred for general-purpose low-noise AC coupling. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262CPW provides optimal balance of low noise (12 nV/√Hz), ultra-low input bias (1 pA), and micropower operation (500 µA) - making it uniquely suited for high-impedance, battery-constrained signal chains where precision and power coexist.

FAQ
What is the maximum operating temperature range for the TLC2262CPW?
The TLC2262CPW is rated for 0°C to 70°C ambient operating temperature (C-suffix grade). This is confirmed in the "TLC2262 AVAILABLE OPTIONS" table, where TLC2262CPW is listed under the 0°C to 70°C row with 2.5 mV max input offset voltage. It is not qualified for extended temperature ranges like the I-suffix (–40°C to 125°C) or Q-suffix variants.
Does the TLC2262CPW support true single-supply operation with input signals down to ground?
Yes, the TLC2262CPW supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), and the input voltage range is specified from VDD– to VDD+ – 1.5 V. At 5 V supply, this allows inputs from 0 V to 3.5 V - enabling direct connection of ground-referenced sensors without external biasing networks.
What is the typical output drive capability of the TLC2262CPW at 5 V supply?
The TLC2262CPW delivers ±50 mA short-circuit output current and maintains rail-to-rail swing into 10 kΩ loads. At 5 V supply with 500 µA supply current, it sustains 4.99 V high-level output at –20 µA load and 0.01 V low-level output at +50 µA load - sufficient to drive ADC reference buffers, LED drivers, or small MOSFET gates directly.
How does the noise performance of the TLC2262CPW compare to the older TLC27M2 series?
The TLC2262CPW offers dramatically improved noise performance versus the TLC27M2: 12 nV/√Hz input voltage noise at 1 kHz (vs. ~25 nV/√Hz for TLC27M2) and 0.6 fA/√Hz input current noise. This 2× reduction in voltage noise directly improves SNR in sensor front-ends, especially when paired with high-source-impedance transducers like piezoelectrics or photodiodes.
Is the TLC2262CPW pin-compatible with the TLC2262CP (PDIP-8) or TLC2262CD (SOIC-8)?
Yes, the TLC2262CPW (TSSOP-8) shares identical pinout and electrical specifications with TLC2262CP (PDIP-8) and TLC2262CD (SOIC-8), as confirmed in the "D, P, OR PW PACKAGE (TOP VIEW)" diagram on page 3 of the datasheet. All three use the same 1–8 pin numbering: OUT A, IN– A, IN+ A, GND, VDD+, IN+ B, IN– B, OUT B.
