Product details
Overview
TS462CDT from STMicroelectronics is a dual rail-to-rail output operational amplifier in SO-8 package, operating from 2.7 V to 10 V supply, delivering ±2.4 V output swing at ±2.5 V supply, with 4 nV/√Hz input noise and 0.003 % THD at 1 kHz - used in microphone pre-amplifiers and portable audio playback circuits.
For engineers reviewing the TS462CDT datasheet, TS462CDT pinout, TS462CDT application, or TS462CDT equivalent, key selection criteria include rail-to-rail output swing under low-voltage battery operation, low-noise performance for analog front-end signal conditioning, and SO-8 compatibility with legacy audio PCB layouts.
Technical Context
The TS462CDT integrates two independent op-amps sharing a common supply (VCC/VDD), each featuring rail-to-rail output stage capable of ±2.4 V swing at ±2.5 V supply and supporting common-mode input range from VDD +1.15 V to VCC −1.15 V. It uses bipolar input stage architecture with 2.8 mA typical supply current per amplifier.
Its 12 MHz gain-bandwidth product and 4 V/µs slew rate support high-fidelity audio signal amplification up to 20 kHz with minimal phase distortion; input offset voltage is specified at 1–7 mV over temperature, and CMRR is 60–85 dB across operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply or split-supply operation in battery-powered audio systems. |
| Output Swing (±2.5 V) | ±2.4 V - enables full dynamic range utilization near supply rails without clipping in 5 V audio signal chains. |
| Input Noise Density | 4 nV/√Hz - ensures minimal audible hiss in microphone pre-amplifier gain stages. |
| THD @ 1 kHz | 0.003 % - preserves harmonic integrity in line-level and headphone driver applications. |
| Gain-Bandwidth Product | 12 MHz - provides stable unity-gain operation and sufficient margin for 20 kHz closed-loop bandwidth. |
| Slew Rate | 4 V/µs - prevents slew-induced distortion on fast transients in multimedia audio waveforms. |
| Common-Mode Input Range | VDD +1.15 V to VCC −1.15 V - allows direct coupling of AC signals biased mid-supply in single-ended configurations. |
Pinout & Package
TS462CDT is housed in an SO-8 (Small Outline) plastic package with standard 1.27 mm pitch, 5.0 mm × 6.2 mm body size, and exposed pad not present. Pin numbering follows JEDEC MS-012AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | Differential input node for first op-amp; accepts feedback network for inverting configuration. |
| 2 | Non-inverting Input (Amplifier A) | Reference input for Amplifier A; used in non-inverting gain stages or buffer configurations. |
| 3 | Output (Amplifier A) | Class-AB rail-to-rail output stage driving loads ≥2 kΩ; compatible with 100 pF capacitive load. |
| 4 | VDD (Negative Supply) | Ground or negative rail connection; must be decoupled locally with 100 nF ceramic capacitor. |
| 5 | VCC (Positive Supply) | Positive supply input; shared by both amplifiers; requires local 100 nF ceramic decoupling. |
| 6 | Output (Amplifier B) | Second independent rail-to-rail output; electrically isolated from Amplifier A except via shared supplies. |
| 7 | Non-inverting Input (Amplifier B) | Reference input for second op-amp; supports differential pair or active filter topology. |
| 8 | Inverting Input (Amplifier B) | Feedback node for Amplifier B; enables dual-channel instrumentation or stereo pre-amplifier designs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | ±2.4 V at ±2.5 V supply - maximizes signal headroom in low-voltage portable audio systems. |
| Low input voltage noise | 4 nV/√Hz - reduces audible noise floor in high-gain microphone pre-amplifier stages. |
| Ultra-low THD | 0.003 % at 1 kHz - maintains fidelity in CD player and sound card line-output drivers. |
| Wide supply range | 2.7 V to 10 V - supports single 3.3 V, 5 V, or split ±2.5 V supplies without redesign. |
| Stable with capacitive loads | Up to 100 pF - eliminates need for isolation resistors when driving ADC inputs or cable capacitance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower supply current (650 µA/ch), lower GBW (6.4 MHz), higher input offset (2 mV typ) | Better suited for ultra-low-power battery monitoring; insufficient GBW for 20 kHz audio fidelity | Select only if power budget <1 mW/ch dominates over THD and bandwidth requirements |
| OPA2340UA | Higher noise (8 nV/√Hz), higher THD (0.005 %), same SO-8 package and rail-to-rail output | Acceptable for line-level distribution but marginal for mic pre-amplifier SNR targets | Prefer when cost sensitivity outweighs 4 dB SNR penalty in low-gain stages |
Compared with TLV2462IDR and OPA2340UA, TS462CDT uniquely balances 4 nV/√Hz noise, 0.003 % THD, and 12 MHz GBW in SO-8 - making it optimal for dual-channel audio signal chains where fidelity and supply flexibility coexist.

FAQ
Is TS462CDT unity-gain stable?
Yes, TS462CDT is unity-gain stable per datasheet Table 3 and Figure 12 (open-loop gain vs. frequency). Its internal compensation ensures phase margin >60° at unity gain with 2 kΩ load and 100 pF capacitance, eliminating need for external compensation networks in standard configurations.
Can TS462CDT operate from a single 3.3 V supply?
Yes, TS462CDT operates from 2.7 V to 10 V single-supply configurations. With 3.3 V supply, its output swing reaches 0.1 V to 3.2 V (rail-to-rail), and common-mode input range spans 1.15 V to 2.15 V - enabling direct coupling of AC signals biased at 1.65 V.
What is the maximum capacitive load TS462CDT can drive?
TS462CDT drives up to 100 pF capacitive load while maintaining stability and specified slew rate, as verified in datasheet Figure 14 (small-signal step response). For loads >100 pF, a 10 Ω series resistor at the output is recommended to isolate capacitance and preserve phase margin.
Does TS462CDT have ESD protection on all pins?
Yes, TS462CDT features 2 kV HBM and 1.5 kV CDM ESD protection on all pins per datasheet Table 1. This meets IEC 61000-4-2 Level 2 requirements and allows safe handling during manual PCB assembly without special grounding protocols.
