Texas Instruments TLC2262CP

Overview

TLC2262CP 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 0.55 V/µs slew rate, 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA maximum supply current, and rail-to-rail output swing - enabling high-fidelity interfacing with low-voltage ADCs in battery-powered instrumentation.

For engineers reviewing the TLC2262CP datasheet, TLC2262CP pinout, TLC2262CP application, or TLC2262CP equivalent, this device is selected for low-noise, micropower analog front-ends where input bias current and output dynamic range are critical - especially in piezoelectric sensor interfaces, portable medical monitors, and industrial 4–20 mA loop receivers requiring stable DC accuracy and wide common-mode input range down to the negative rail.

Technical Context

The TLC2262CP uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) while maintaining rail-to-rail output capability across ±2.2 V to ±8 V supplies. Its input stage operates with common-mode voltage extending to the negative rail, supporting true single-supply operation without level-shifting circuitry.

Internally, it features fully differential CMOS input pairs with matched trimming for offset control, low-noise transconductance stages, and a Class AB output buffer optimized for capacitive load drive up to 100 pF. The architecture balances ac performance (0.71 MHz GBW, 56° phase margin) and dc precision (3 mV max VIO at 25°C) without micropower trade-offs seen in TLC225x family devices.

FAQ

What is the maximum supply voltage rating for the TLC2262CP?

The TLC2262CP has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD– terminals. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.2 V to ±8 V, with full electrical characterization validated at ±5 V and +5 V single-supply configurations. Derating is not required within these bounds.

Does the TLC2262CP support true single-supply operation with input signals near ground?

Yes, the TLC2262CP supports true single-supply operation: its common-mode input voltage range includes the negative rail (GND when VDD– = GND), allowing inputs down to 0 V. This eliminates the need for input biasing networks in +5 V systems - critical for interfacing with grounded sensors or DAC outputs.

How does the input offset voltage of the TLC2262CP compare to the TLC2262AIP variant?

The TLC2262CP has a maximum input offset voltage of 2.5 mV at 25°C, whereas the TLC2262AIP (A-grade) is specified at 950 µV max under identical conditions. Both share the same pinout and package, but the A-grade version undergoes tighter trimming for higher-precision applications such as weigh scales or calibration references.

Can the TLC2262CP drive capacitive loads without instability?

The TLC2262CP is unity-gain stable with capacitive loads up to 100 pF when configured with RL ≥ 50 kΩ, as verified by 56° phase margin and 11 dB gain margin in the datasheet. For loads >100 pF, external isolation resistance (e.g., 10 Ω in series with output) is recommended to maintain stability in high-impedance sensor buffering applications.

Is the TLC2262CP pin-compatible with older TI op-amps like the TLC27M2CP?

No - while the TLC2262CP serves as a performance upgrade to the TLC27M2CP, it is not pin-compatible. The TLC27M2CP uses a different pinout (e.g., Pin 1 = Output, Pin 2 = Inverting Input), whereas the TLC2262CP follows standard dual-op-amp pin mapping (Pin 1 = Inverting Input, Pin 2 = Non-Inverting Input). PCB redesign is required for migration.
