Texas Instruments TLC2202CPS

Overview

TLC2202CPS from Texas Instruments is a dual, precision, low-noise operational amplifier using Advanced LinCMOS™ process. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, rail-to-rail output swing, and operates from ±2.3 V to ±8 V supplies. It serves as a signal-conditioning front-end in high-impedance sensor interfaces and single-supply data acquisition systems.

For engineers reviewing the TLC2202CPS datasheet, TLC2202CPS pinout, TLC2202CPS application, or TLC2202CPS equivalent, key selection criteria include its 0.5 µV/°C offset drift stability, 1 pA typical input bias current, common-mode input range extending to the negative rail, and compatibility with both single- and split-supply configurations.

Technical Context

The TLC2202CPS integrates two independent precision op-amps on a single die using silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over temperature and time versus metal-gate processes. Its input stage includes JFET-like high impedance (1 pA I_IB) while maintaining bipolar-level DC precision.

It features fully specified operation across 0°C to 70°C, supports rail-to-rail output swing into 10 kΩ loads, and withstands −100 mA surge currents at inputs/outputs without latch-up. Internal ESD protection meets 2000 V HBM per MIL-PRF-38535 Method 3015.2.

FAQ

What is the maximum supply voltage rating for the TLC2202CPS?

The TLC2202CPS has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD− terminals. Operation beyond this limit risks permanent damage. The recommended operating range is ±2.3 V to ±8 V, with full electrical specifications guaranteed across that span. Derating is not required within this range, and the device maintains rail-to-rail output performance at ±5 V and ±8 V supplies.

Does the TLC2202CPS support true rail-to-rail input operation?

No, the TLC2202CPS does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ − 2.3 V under recommended conditions. For example, with ±5 V supplies, the valid input range is −5 V to +2.7 V. This design enables robust operation with ground-referenced sensors while maintaining precision-unlike true rail-to-rail input op-amps, which often trade off CMRR or noise performance.

Can the TLC2202CPS drive capacitive loads directly?

The TLC2202CPS is stable with capacitive loads ≤100 pF when driving a 10 kΩ resistive load, as verified by phase margin testing (48° at unity gain). For larger capacitive loads (e.g., ADC input capacitance >100 pF), an isolation resistor (20–100 Ω) between the TLC2202CPS output and the load is required to maintain stability and prevent peaking or oscillation. This is explicitly documented in the datasheet's "Capacitive Load Driving" section.

What is the typical input bias current of the TLC2202CPS, and how does it vary with temperature?

The TLC2202CPS exhibits 1 pA typical input bias current at 25°C, with a maximum of 100 pA across the full 0°C to 70°C operating range. Unlike bipolar-input op-amps, its Advanced LinCMOS™ process ensures minimal temperature dependence-bias current remains within 1–2 pA from 0°C to 50°C and rises gradually to ≤100 pA only near 70°C. This stability is essential for high-impedance source applications like photodiode transimpedance stages.

Is the TLC2202CPS pin-compatible with other devices in the TLC220x family?

Yes, the TLC2202CPS shares identical pinout and footprint with all PS-package variants in the TLC220x family, including TLC2202ACPS, TLC2202BCPS, and TLC2202IPS. All PS-packaged TLC2202 devices use the same 8-pin SOIC layout with Pin 1 = Amp1(−), Pin 2 = Amp1(+), Pin 3 = Amp1(Output), Pin 4 = VDD−/GND, Pin 5 = VDD+, Pin 6 = Amp2(−), Pin 7 = Amp2(+), Pin 8 = Amp2(Output). This allows drop-in substitution based on grade (C/I/M) and noise/offset binning without PCB changes.
