Product details
Overview
TS462CST from STMicroelectronics is a dual rail-to-rail output operational amplifier in MiniSO-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 pre-amplification in portable multimedia devices.
For engineers reviewing the TS462CST datasheet, TS462CST pinout, TS462CST application, or TS462CST equivalent, key selection criteria include rail-to-rail output swing under low supply, audio-grade noise/distortion performance, dual-channel integration in MiniSO-8, and compatibility with battery-powered microphone and line-level signal paths.
Technical Context
The TS462CST implements a dual-channel, internally compensated voltage-feedback op-amp architecture optimized for single- or split-supply audio signal chains. Each channel supports rail-to-rail output swing down to 2.7 V total supply and maintains 8.5–12 MHz gain-bandwidth product with 2.8–4 V/µs slew rate.
Its input stage uses bipolar transistor topology to achieve low input offset voltage (1–7 mV), low drift (5 µV/°C), and high common-mode rejection (60–85 dB) across -20 °C to +70 °C operating range - critical for DC-coupled microphone preamps and analog audio codecs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct operation from single Li-ion cell (3.0–3.7 V) or dual alkaline (3 V) without LDO regulation |
| Output Swing | ±2.4 V at ±2.5 V supply - delivers >96 % of full rail-to-rail dynamic range for 16-bit ADC input headroom |
| Input Noise Density | 4 nV/√Hz at 100 kHz - preserves SNR in condenser mic preamp stages with <10 kΩ source impedance |
| Total Harmonic Distortion | 0.003 % at 1 kHz, AV = -1, RL = 10 kΩ - meets CD-quality audio linearity requirements |
| Gain-Bandwidth Product | 8.5–12 MHz - supports stable unity-gain and inverting configurations up to 200 kHz audio bandwidth |
| Slew Rate | 2.8–4 V/µs - prevents slew-induced distortion on 1 Vpp, 20 kHz sine wave signals |
| Common-Mode Rejection | 60–85 dB - rejects power supply ripple and PCB coupling in compact portable layouts |
Pinout & Package
TS462CST is housed in MiniSO-8 package (3.0 mm × 4.9 mm, 0.65 mm pitch), a thermally enhanced, surface-mount variant of SO-8 with reduced footprint and improved thermal resistance (103 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance differential node for feedback network connection in inverting amplifier configuration |
| 2 | Non-inverting Input (Channel A) | DC-biased reference point for single-supply AC-coupled microphone preamp stage |
| 3 | Output (Channel A) | Rail-to-rail capable output driving 10 kΩ load with <0.003 % THD at 1 kHz |
| 4 | VCC (Positive Supply) | Primary positive rail connection; accepts 2.7–10 V; decoupling capacitor required within 5 mm |
| 5 | VDD (Negative Supply / GND) | Ground or negative rail; supports split-supply (±2.5 V) or single-supply (GND) operation |
| 6 | Inverting Input (Channel B) | Independent input for stereo channel or differential receiver stage |
| 7 | Non-inverting Input (Channel B) | Separate biasing path for second channel; allows independent gain setting per channel |
| 8 | Output (Channel B) | Second rail-to-rail output; electrically isolated from Channel A except shared supply pins |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >95 % of supply rails across full temperature range, preserving dynamic range in low-voltage audio DAC buffers |
| Low input voltage noise | 4 nV/√Hz enables <70 dB(A) self-noise floor in electret mic preamps with 2.2 kΩ feedback resistor |
| Ultra-low harmonic distortion | 0.003 % THD ensures minimal intermodulation in multi-tone audio playback and recording paths |
| Wide supply voltage range | 2.7–10 V operation eliminates need for dedicated audio LDO in mixed-signal portable systems |
| MiniSO-8 thermal performance | 103 °C/W junction-to-ambient enables 2× continuous output current vs. SOT23-5 without derating at +70 °C ambient |

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 input offset (2 mV typ), lower GBW (2.2 MHz), higher supply current (1.3 mA/ch) | Less suitable for high-fidelity 20 kHz audio due to limited bandwidth and higher distortion (0.01 % THD) | Select when cost sensitivity outweighs audio fidelity and board space constraints |
| OPA2340UA | Lower noise (7 nV/√Hz), higher quiescent current (800 µA/ch), SO-8 only (no MiniSO-8 option) | Larger thermal resistance (125 °C/W) limits output drive capability in compact enclosures | Prefer for ultra-low-distortion applications where PCB layout allows larger SO-8 and higher supply budget |
Compared with TLC2272CDR and OPA2340UA, TS462CST offers optimal balance of audio performance (4 nV/√Hz, 0.003 % THD), MiniSO-8 space efficiency, and 2.7–10 V supply flexibility - making it the preferred choice for space-constrained, battery-powered audio front-ends requiring CD-quality linearity.

FAQ
What is the maximum output current capability of TS462CST?
TS462CST delivers ±30 mA short-circuit output current per channel, with typical continuous output current of ±15 mA into 600 Ω loads at room temperature. This supports direct driving of line outputs and low-impedance headphones with external series resistors, but not full-power headphone loads without external buffering.
Can TS462CST operate from a single 3.3 V supply?
Yes - TS462CST operates from 2.7 V to 10 V single supply. With 3.3 V, it provides >2.6 Vpp rail-to-rail output swing and maintains 0.003 % THD at 1 kHz. Input common-mode range extends from VDD + 1.15 V to VCC − 1.15 V, allowing direct AC-coupled microphone input at 3.3 V.
Is TS462CST pin-compatible with other TS46x variants?
No - TS462CST (MiniSO-8) has different pinout than TS462CDT (SO-8) and TS462CPT (TSSOP-8). While all share identical electrical characteristics, mechanical layout differs: MiniSO-8 places VDD on Pin 5 and uses smaller pad pitch (0.65 mm), requiring separate PCB footprint design.
Does TS462CST include ESD protection on all pins?
Yes - TS462CST features 2 kV HBM, 200 V MM, and 1.5 kV CDM ESD protection on all pins per JEDEC standards. This enables robust handling during assembly and operation in consumer environments without external TVS diodes on analog signal paths.
