STMicroelectronics TS27L2CDT

Overview

TS27L2CDT from STMicroelectronics is a precision, very low power CMOS dual operational amplifier in SO-8 package, featuring 10 µA per amplifier supply current, 0.25 mV max input offset voltage (TS27L2C grade), rail-to-ground output swing, and 0.1 MHz gain-bandwidth product. It operates from 3 V to 16 V single supply and is used in battery-powered sensor signal conditioning and portable medical instrumentation.

For engineers reviewing the TS27L2CDT datasheet, TS27L2CDT pinout, TS27L2CDT application, or TS27L2CDT equivalent, key selection criteria include ultra-low quiescent current, guaranteed low offset voltage at room temperature, capacitive-load stability up to 100 pF, and SO-8 tape-and-reel availability for automated assembly.

Technical Context

This dual op-amp uses ST's silicon-gate CMOS process to achieve high input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its two-stage architecture delivers stable unity-gain operation with ≥45° phase margin into 100 pF loads without external compensation.

The device supports single-supply operation with common-mode input range extending to ground and output swing to within 50 mV of ground. Input offset voltage is factory-trimmed across three grades (C/A/B), with TS27L2C offering 0.25 mV max at 25°C and 2 µV/°C drift.

Key Specifications

Pinout & Package

FAQ

What is the maximum capacitive load the TS27L2CDT can drive without oscillation?

The TS27L2CDT maintains ≥45° phase margin and stable unity-gain operation with up to 100 pF capacitive load, as verified in Figure 8 of the official datasheet. For loads exceeding 100 pF, a series isolation resistor (≥100 Ω) between output and capacitance is recommended to preserve stability.

Does TS27L2CDT support true single-supply operation from 3 V?

Yes. TS27L2CDT operates from 3 V to 16 V single supply, with common-mode input range specified from 0 V to V_CC − 1.5 V and output swing to within 50 mV of ground. At 3 V supply, output reaches down to 0.05 V and up to 2.9 V under light load, enabling direct interfacing with 3.3 V microcontrollers.

How does the TS27L2C grade differ from TS27L2AC and TS27L2BC in production test?

The TS27L2C grade undergoes full offset voltage screening to guarantee ≤0.25 mV at 25°C, while TS27L2AC and TS27L2BC are binned to ≤0.9 mV and ≤1.1 mV respectively. All grades share identical supply current (10 µA), bias current (1 pA), and phase margin specs-only offset voltage and its temperature drift (2 µV/°C) are grade-differentiating parameters.

Is the SO-8 package of TS27L2CDT RoHS-compliant and halogen-free?

Yes. TS27L2CDT is manufactured in STMicroelectronics' RoHS-compliant, lead-free, and halogen-free SO-8 package per specification ECOPACK®2. The "DT" suffix confirms tape-and-reel packaging meets IPC-7351B Class B standards and is compatible with standard SMT pick-and-place equipment.
