Product details
Overview
TS464CDT from STMicroelectronics is a quad rail-to-rail output operational amplifier optimized for audio signal conditioning in portable battery-powered systems. It operates from 2.7 V to 10 V single supply (or ±2.5 V dual), delivers ±2.4 V output swing, features 4 nV/√Hz input voltage noise and 0.003 % THD at 1 kHz, and is housed in an SO-14 package. It serves as a low-noise, low-distortion preamplifier and line driver in multimedia audio front-ends.
For engineers reviewing the TS464CDT datasheet, TS464CDT pinout, TS464CDT application, or TS464CDT equivalent, key selection criteria include its rail-to-rail output swing under low-voltage operation, 8.5–12 MHz gain-bandwidth product, 2.8–4 V/µs slew rate, and SO-14 thermal resistance of 103 °C/W - all critical for high-fidelity portable audio signal chain design.
Technical Context
The TS464CDT integrates four independent op-amps sharing a common supply domain, each with rail-to-rail output stage enabling full dynamic range utilization near supply rails. Its input common-mode range extends from VDD +1.15 V to VCC −1.15 V, supporting biasing flexibility in AC-coupled audio paths.
Designed for low-voltage audio applications, it achieves 60–85 dB common-mode rejection and 60–70 dB supply voltage rejection across temperature, with input offset voltage drift of only 5 µV/°C - ensuring stable DC operating points in multi-stage microphone or line-level amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V single supply (±2.5 V dual) - enables direct integration into 3.3 V or 5 V portable audio systems without level-shifting. |
| Output Swing | ±2.4 V at VCC = ±2.5 V - 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 - minimizes audible hiss in microphone preamplifier stages and analog audio signal chains. |
| THD+N | 0.003 % at 1 kHz, AV = −1, RL = 10 kΩ - meets CD-quality distortion requirements for line-level output drivers. |
| Gain-Bandwidth Product | 8.5–12 MHz - supports stable unity-gain and moderate-gain configurations up to ~200 kHz for wideband audio bandwidth. |
| Slew Rate | 2.8–4 V/µs - preserves transient fidelity of percussive audio signals without slew-induced distortion. |
| Input Offset Voltage | 1–7 mV over temperature - ensures minimal DC error accumulation in multi-op-amp audio filters or summing nodes. |
Pinout & Package
TS464CDT is packaged in a 14-lead SOIC (SO-14) with standard 1.27 mm pitch, offering 103 °C/W junction-to-ambient thermal resistance and compatibility with automated PCB assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp 1) | High-impedance differential input node for first op-amp; referenced to common-mode voltage range VDD +1.15 V to VCC −1.15 V. |
| 2 | Non-inverting Input (Amp 1) | Second high-Z input for Amp 1; enables inverting/non-inverting configurations per channel. |
| 3 | Output (Amp 1) | Rail-to-rail output capable of sourcing/sinking current into 2 kΩ load while maintaining ±2.4 V swing at ±2.5 V supply. |
| 4 | VDD (Negative Supply) | Ground or negative rail connection; must be decoupled locally to minimize PSRR degradation and noise coupling. |
| 5 | Inverting Input (Amp 2) | Dedicated input for second op-amp; electrically isolated from other channels except shared supply pins. |
| 6 | Non-inverting Input (Amp 2) | Independent input for Amp 2; supports dual-channel stereo preamp or filter implementation. |
| 7 | Output (Amp 2) | Second rail-to-rail output; matched performance to Pin 3 for balanced stereo signal processing. |
| 8 | VCC (Positive Supply) | Main positive supply rail; requires 100 nF ceramic decoupling capacitor placed within 5 mm of this pin. |
| 9 | Inverting Input (Amp 3) | Third op-amp input; enables triple-stage filtering or multi-path signal routing in compact layouts. |
| 10 | Non-inverting Input (Amp 3) | Complementary input for Amp 3; maintains same CMVR and input bias specs as other channels. |
| 11 | Output (Amp 3) | Third independent output; usable for auxiliary functions like headphone buffer or tone control feedback path. |
| 12 | Inverting Input (Amp 4) | Fourth op-amp input; allows full quad configuration for complex audio mixing or active crossover networks. |
| 13 | Non-inverting Input (Amp 4) | Final input channel; identical electrical characteristics to Pins 1, 5, and 9. |
| 14 | Output (Amp 4) | Fourth rail-to-rail output; supports simultaneous stereo left/right plus monitor and effects send paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers ±2.4 V into 2 kΩ load at ±2.5 V supply - maximizes usable dynamic range in 3.3 V or 5 V audio systems. |
| Low input voltage noise | 4 nV/√Hz at 100 kHz - directly reduces audible noise floor in microphone preamplifier gain stages. |
| Ultra-low harmonic distortion | 0.003 % THD+N at 1 kHz - satisfies CD-quality line-level output specifications without post-filtering. |
| Wide supply voltage range | Operates from 2.7 V to 10 V single supply - eliminates need for dedicated ±5 V rails in portable designs. |
| Stable over temperature | Input offset drift of only 5 µV/°C - prevents DC drift-induced pop/click in multi-stage audio signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS464IDT | Wider operating temperature range (−40 °C to +85 °C) vs. TS464CDT (−20 °C to +70 °C); otherwise identical electrical specs and pinout. | Required for industrial or extended-temperature consumer devices; not suitable for cost-sensitive commercial audio where ambient stays within −20 °C to +70 °C. | Select TS464IDT when board-level thermal environment exceeds 70 °C ambient or requires automotive-grade qualification margin. |
| LMV324DR | Lower GBW (1 MHz), higher input offset (7 mV max), no rail-to-rail output (swing limited to VCC −0.7 V), but lower quiescent current (120 µA/op-amp). | Suitable for low-power sensor signal conditioning, not audio - insufficient bandwidth and distortion performance for CD-quality reproduction. | Choose LMV324DR only for non-audio, low-speed, ultra-low-power applications where audio fidelity is irrelevant. |
Compared with TS464IDT, TS464CDT trades extended temperature capability for lower unit cost in commercial audio gear; versus LMV324DR, it delivers 12× higher bandwidth, 4× lower THD, and true rail-to-rail output - making it the sole viable option for fidelity-critical portable audio stages.

FAQ
What is the maximum recommended supply voltage for TS464CDT?
The absolute maximum supply voltage is 12 V, but the device is characterized and guaranteed for reliable operation between 2.7 V and 10 V. Operating above 10 V risks exceeding internal junction temperature limits and may degrade long-term reliability, especially in SO-14 packages with 103 °C/W thermal resistance.
Can TS464CDT drive 32 Ω headphones directly?
No - TS464CDT is not specified for direct low-impedance headphone driving. Its output stage is rated for ≥2 kΩ loads; driving 32 Ω loads causes excessive current demand, thermal stress, and distortion beyond datasheet limits. Use a dedicated headphone amplifier IC or discrete output stage instead.
Does TS464CDT require external compensation for unity-gain stability?
No - TS464CDT is internally compensated and stable at unity gain. The datasheet confirms stable operation with RL = 2 kΩ and CL = 100 pF, and no external compensation components are needed for standard gain configurations up to AV = 100.
Is the TS464CDT RoHS-compliant and lead-free?
Yes - TS464CDT is manufactured in ST's ECOPACK2-compliant SO-14 package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. Lead-free soldering profiles up to 250 °C (10 sec) are supported, as confirmed in the absolute maximum ratings table.
