Product details
Overview
TS462CN from STMicroelectronics is a dual rail-to-rail output operational amplifier optimized for low-voltage audio signal conditioning in portable equipment. It operates from 2.7 V to 10 V single supply (or ±1.35 V to ±5 V dual supply), delivers ±2.4 V output swing at ±2.5 V supply, features 4 nV/√Hz input voltage noise and 0.003 % THD at 1 kHz - enabling high-fidelity microphone pre-amplification and line-level audio buffering.
For engineers reviewing the TS462CN datasheet, TS462CN pinout, TS462CN application, or TS462CN equivalent, key selection criteria include rail-to-rail output swing under low supply voltage, ultra-low distortion for audio fidelity, noise performance below 5 nV/√Hz, and SOT23-5 footprint compatibility with space-constrained portable designs.
Technical Context
The TS462CN implements a complementary input stage with rail-to-rail output stage, enabling full-swing operation down to 2.7 V single supply. Its 8.5–12 MHz gain-bandwidth product supports stable unity-gain and inverting configurations up to audio frequencies without phase margin degradation.
Designed for battery-powered systems, it achieves 2.8 mA per amplifier supply current while maintaining 2.8–4 V/µs slew rate and 60–85 dB common-mode rejection - critical for rejecting power rail noise in shared-supply audio subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V single supply (±1.35 V to ±5 V dual) - enables direct integration into 3.3 V or 5 V portable systems without level-shifting. |
| Output Swing | ±2.4 V at ±2.5 V supply - delivers >96 % of full rail-to-rail dynamic range for maximum SNR in low-voltage audio paths. |
| Input Voltage Noise | 4 nV/√Hz at 100 kHz - preserves signal integrity in microphone pre-amplifier gain stages where noise dominates dynamic range. |
| Total Harmonic Distortion | 0.003 % at 1 kHz, AV = −1, RL = 10 kΩ - meets CD-quality audio linearity requirements without post-processing correction. |
| Gain-Bandwidth Product | 8.5–12 MHz - supports stable 20× closed-loop gain up to 500 kHz, covering full audio band with margin for filter roll-off. |
| Slew Rate | 2.8–4 V/µs - prevents slew-induced distortion on 1 Vpp 20 kHz signals, ensuring clean transient response in recording equipment. |
| Common-Mode Rejection | 60–85 dB - suppresses supply ripple and ground bounce coupling in mixed-signal PCB layouts with shared analog/digital rails. |
Pinout & Package
TS462CN is housed in a 5-pin SOT23-5 micropackage (ECOPACK® compliant), measuring 2.90 mm × 1.60 mm × 1.10 mm (max), suitable for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance differential input node for feedback configuration; referenced to VDD for single-supply biasing. |
| 2 | Non-inverting Input (Channel A) | Direct connection point for sensor or signal source; CMVR extends to VDD +1.15 V and VCC −1.15 V. |
| 3 | Output (Channel A) | Rail-to-rail output capable of sourcing/sinking ≥10 mA; drives 2 kΩ loads with <10 mV saturation error. |
| 4 | VDD / Positive Supply | Primary power terminal for single-supply operation; accepts 2.7–10 V; decoupling capacitor required within 5 mm. |
| 5 | VCC / Negative Supply or Ground | Return path for dual-supply (−V) or GND reference in single-supply mode; must be low-impedance to minimize PSRR degradation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers ±2.4 V output at ±2.5 V supply - maximizes usable dynamic range in 3.3 V systems without external charge pumps. |
| Low-noise architecture | 4 nV/√Hz input voltage noise - reduces integrated noise floor in 20 Hz–20 kHz bandwidth to <1.2 µV RMS for clean pre-amplification. |
| Ultra-low distortion | 0.003 % THD at 1 kHz - eliminates audible harmonic artifacts in CD player DAC output buffers and headphone drivers. |
| Wide supply range | Operates from 2.7 V to 10 V - supports direct use across Li-ion (3.0–4.2 V), USB (5 V), and legacy 9 V battery systems. |
| Thermal robustness | RthJA = 250 °C/W (SOT23-5) - allows continuous 2.8 mA per channel operation at ambient ≤60 °C without heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail audio op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272CDR | Higher supply current (1.1 mA/channel), lower GBW (2.2 MHz), higher noise (10 nV/√Hz) | Acceptable for line-level buffering but marginal for microphone pre-amplification due to noise floor | Select when cost sensitivity outweighs audio fidelity; verify thermal dissipation in SOT23-8 package |
| OPA2340UA | Lower THD (0.0007 %), higher supply voltage min (2.7 V same), larger SO-8 footprint | Better suited for professional audio interfaces requiring ultra-low distortion, but occupies 3× PCB area | Choose when THD <0.001 % is mandatory and board space permits SO-8; not drop-in compatible |
Compared with TLC2272CDR and OPA2340UA, TS462CN uniquely balances ultra-low noise (4 nV/√Hz), rail-to-rail swing at 2.7 V, and SOT23-5 size - making it optimal for space-constrained, battery-powered audio front-ends where SNR and efficiency are co-prioritized.

FAQ
What is the maximum operating temperature for TS462CN?
The TS462CN has an operating free-air temperature range of −20 °C to +70 °C, validated per DS1416 Rev 4. Junction temperature must not exceed 150 °C; with RthJA = 250 °C/W and 2.8 mA per channel, ambient must stay below 60 °C for continuous operation at 10 V supply.
Can TS462CN operate from a single 3.3 V supply?
Yes - TS462CN supports single-supply operation from 2.7 V to 10 V. At 3.3 V, its common-mode input range is 1.15 V to 2.15 V, and output swings from 0.05 V to 3.25 V (typical), enabling direct interfacing with 3.3 V ADCs and DACs without level-shifting circuitry.
Is TS462CN pin-compatible with other TS46x variants?
No - TS462CN (SOT23-5) is not pin-compatible with TS462CPT (TSSOP-8) or TS462CDT (SO-8). The SOT23-5 variant uses a 5-pin configuration (In−, In+, Out, VDD, VCC/GND), whereas 8-pin versions add shutdown, offset null, or second supply pins not present in the CN variant.
Does TS462CN require external compensation capacitors?
No - TS462CN is unity-gain stable per DS1416 Rev 4 electrical characteristics. Its internal compensation ensures stability with capacitive loads ≤100 pF; for heavier loads (e.g., >500 pF cables), a series resistor (10–47 Ω) between output and load is recommended to prevent peaking.
