STMicroelectronics TS462CPT

Overview

TS462CPT from STMicroelectronics is a dual rail-to-rail output operational amplifier in TSSOP-8 package, designed for low-voltage audio signal conditioning. It operates from 2.7 V to 10 V supply, delivers ±2.4 V output swing at ±2.5 V supply, features 4 nV/√Hz input noise and 0.003 % THD at 1 kHz - enabling high-fidelity microphone pre-amplification and portable multimedia playback.

For engineers reviewing the TS462CPT datasheet, TS462CPT pinout, TS462CPT application, or TS462CPT equivalent, key selection criteria include rail-to-rail output swing under low supply voltage, low distortion in single-supply audio paths, noise performance at 100 kHz, and compatibility with TSSOP-8 layout constraints in space-constrained portable designs.

Technical Context

The TS462CPT integrates two independent op-amps sharing a common supply (VCC/VDD), each with rail-to-rail output stage capable of swinging within 100 mV of either rail under 2 kΩ load. Its input common-mode range extends from VDD +1.15 V to VCC −1.15 V, supporting biasing flexibility in single-supply configurations.

It uses bipolar input stage architecture delivering 8.5–12 MHz gain-bandwidth product and 2.8–4 V/µs slew rate, optimized for unity-gain stable operation with capacitive loads up to 100 pF - critical for driving audio DAC outputs or ADC input buffers without oscillation.

FAQ

What is the maximum capacitive load the TS462CPT can drive without instability?

The TS462CPT is unity-gain stable with up to 100 pF capacitive load, as verified in the datasheet under Electrical Characteristics (Table 3, test condition CL = 100 pF). Driving larger loads requires an isolation resistor (≥10 Ω) in series with the output to maintain phase margin above 45°.

Can TS462CPT operate from a single 3.3 V supply?

Yes - the TS462CPT supports single-supply operation from 2.7 V to 10 V. With VDD = 0 V and VCC = 3.3 V, its input common-mode range spans 1.15 V to 2.15 V, and output swings from 0.1 V to 3.2 V, enabling direct interfacing with 3.3 V ADCs and DACs without level-shifting circuitry.

Does TS462CPT have internal ESD protection?

Yes - the TS462CPT includes on-chip ESD protection rated at 2 kV HBM, 200 V MM, and 1.5 kV CDM per JEDEC standards, as specified in Table 1 of the DS1416 datasheet. This eliminates need for external TVS diodes in typical audio I/O paths.

How does TS462CPT's THD compare to TS461 and TS464 variants?

All three variants (TS461, TS462, TS464) share identical THD specification: 0.003 % at 1 kHz, AV = −1, RL = 10 kΩ, per Table 3. The difference lies in channel count (single/dual/quad) and package options - not in audio linearity performance.
