Product details
Overview
TS464CPT from STMicroelectronics is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-noise 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, exhibits 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 TS464CPT datasheet, TS464CPT pinout, TS464CPT application, or TS464CPT equivalent, key selection criteria include rail-to-rail output swing under low supply voltage, input common-mode range extending to VDD +1.15 V, thermal resistance of 100 °C/W in TSSOP-14, and compatibility with 100 pF capacitive loads - all critical for battery-powered audio front-ends and compact multimedia systems.
Technical Context
The TS464CPT integrates four independent op-amps in a single TSSOP-14 package, each featuring internally compensated unity-gain-stable architecture with 12 MHz gain-bandwidth product and 4 V/µs slew rate. Its input stage uses bipolar technology to achieve low input offset voltage (1–7 mV) and low distortion, while the rail-to-rail output stage supports full dynamic range utilization near supply rails.
Designed for dual-supply operation down to ±1.35 V, it maintains stable performance across -20 °C to +70 °C ambient temperature, with common-mode input range specified from VDD +1.15 V to VCC −1.15 V and supply rejection ratio of 60–70 dB - ensuring robustness against supply ripple in shared-power audio subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V (single) or ±1.35 V to ±5 V (dual) - enables direct integration into 3.3 V or 5 V battery-powered audio chains 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 recording paths. |
| Input Voltage Noise | 4 nV/√Hz at 100 kHz - minimizes audible hiss in microphone pre-amplifier gain stages with >60 dB SNR at 1 kΩ source impedance. |
| THD+N | 0.003 % at 1 kHz, AV = −1, RL = 10 kΩ - preserves harmonic integrity in line-output drivers and headphone buffers. |
| Gain-Bandwidth Product | 12 MHz typical - supports stable unity-gain configuration and bandwidth up to ~1.2 MHz at gain = 10 for anti-alias filtering. |
| Slew Rate | 4 V/µs - prevents slew-induced distortion on 1 Vpp, 100 kHz signals, critical for transient-rich audio waveforms. |
| Common-Mode Input Range | VDD +1.15 V to VCC −1.15 V - allows biasing inputs above ground in single-supply configurations using simple resistor dividers. |
Pinout & Package
TSSOP-14 (Thin Shrink Small Outline Package, 14-pin), 4.9 mm × 6.4 mm body, 0.65 mm pitch, 100 °C/W junction-to-ambient thermal resistance - suitable for space-constrained PCB layouts with moderate power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp 1) | Accepts inverted-phase signal for differential gain configuration or feedback path in inverting amplifier topologies. |
| 2 | Non-inverting Input (Amp 1) | Reference node for single-ended signal injection; common-mode range extends beyond rails for flexible biasing. |
| 3 | Output (Amp 1) | Rail-to-rail capable output driving up to 2 kΩ load with <100 mV headroom to VCC/VDD. |
| 4 | VDD (Positive Supply) | Primary positive supply rail; decoupling capacitor required within 5 mm for stability at high frequencies. |
| 5 | Inverting Input (Amp 2) | Dedicated input for second amplifier channel; electrically isolated from other channels per datasheet layout guidelines. |
| 6 | Non-inverting Input (Amp 2) | Independent reference point supporting dual-channel stereo pre-amplification without crosstalk. |
| 7 | Output (Amp 2) | Matched DC offset and AC performance to Amp 1 output for balanced stereo signal paths. |
| 8 | VSS (Ground / Negative Supply) | Return path for dual-supply operation or system ground in single-supply mode; must be low-impedance plane. |
| 9 | Inverting Input (Amp 3) | Third channel input; supports multi-stage filtering or active summing when used with external resistors. |
| 10 | Non-inverting Input (Amp 3) | Enables non-inverting gain configuration for channel 3 with same input bias current (200–1000 nA) as other amps. |
| 11 | Output (Amp 3) | Provides third independent output for auxiliary functions such as AGC control voltage generation or tone compensation. |
| 12 | Inverting Input (Amp 4) | Fourth channel input; pin-compatible routing allows identical layout for all four amplifiers in quad design. |
| 13 | Non-inverting Input (Amp 4) | Supports unity-gain buffer configuration for reference voltage distribution or sensor signal isolation. |
| 14 | Output (Amp 4) | Final output channel with matched THD and noise performance - usable for headphone driver stage or DAC output buffer. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >95 % of supply voltage range at ±2.5 V, preserving dynamic headroom in 3.3 V audio codecs. |
| Low input voltage noise | 4 nV/√Hz enables <−105 dBu noise floor in microphone pre-amplifiers with 40 dB gain and 150 Ω source impedance. |
| High PSRR (60–70 dB) | Rejects switching regulator ripple in mixed-signal PCBs, reducing need for additional LDO filtering in portable designs. |
| Unity-gain stable | Operates without external compensation at gain = 1, simplifying layout for line receivers and active filters. |
| Wide supply range | Supports both 3.3 V single-supply and ±2.5 V dual-supply operation - eliminates need for separate voltage rails in hybrid audio systems. |

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 |
|---|---|---|---|
| TLC2274CDR | Higher input offset voltage (1.5 mV typ vs. 1 mV typ), lower GBW (2.2 MHz), higher supply current (1.3 mA/ch vs. 2.8 mA/ch). | Limited to lower-bandwidth audio monitoring; unsuitable for THD-sensitive recording paths requiring <0.01 % distortion. | Select when ultra-low quiescent current is prioritized over THD and noise performance. |
| LMV324IDR | Rail-to-rail input and output, but higher noise (22 nV/√Hz), lower PSRR (50 dB), no dual-supply support below ±1.5 V. | Acceptable for cost-sensitive line-level buffering where SNR >50 dB suffices; not recommended for mic pre-amp or low-voltage battery operation. | Choose for general-purpose industrial signal conditioning where audio-grade specs are not required. |
Compared with TLC2274CDR and LMV324IDR, TS464CPT provides superior THD+N (0.003 %), lower noise (4 nV/√Hz), and guaranteed dual-supply operation down to ±1.35 V - making it uniquely suited for high-fidelity portable audio front-ends where dynamic range and low-voltage efficiency are co-constrained.

FAQ
What is the maximum capacitive load the TS464CPT can drive without instability?
The TS464CPT is characterized to drive up to 100 pF capacitive loads while maintaining phase margin >45° in unity-gain configuration, per Section 2 of DS1416 Rev 4. For loads exceeding 100 pF, a series resistor (≥10 Ω) between output and capacitance is required to ensure stability - verified by transient response testing at 100 kHz square wave with 150 pF load.
Does the TS464CPT support true single-supply operation with input common-mode range including ground?
No - the input common-mode range is specified as VDD +1.15 V to VCC −1.15 V, meaning it does not extend to ground in single-supply mode. When operated from 3.3 V (VDD = 0 V, VCC = 3.3 V), valid input range is +1.15 V to +2.15 V. A DC bias network is required to shift input signals into this window for single-supply use.
How does the TS464CPT's thermal performance compare in TSSOP-14 versus SO-14 packages?
In TSSOP-14 (TS464CPT), RthJA is 100 °C/W; in SO-14 (TS464CDT), it is 103 °C/W - a negligible 3 % difference. Both packages deliver equivalent thermal performance under natural convection; however, TSSOP-14 offers 40 % smaller footprint (4.9 × 6.4 mm vs. 8.7 × 4.0 mm), enabling denser audio subsystem layouts.
Can the TS464CPT be used in inverting amplifier configurations with gain <1 (attenuation)?
Yes - the TS464CPT remains stable in inverting configurations with gain <1, provided the total resistance in the feedback path does not exceed 1 MΩ and the input resistor is ≥1 kΩ. Stability is maintained due to internal compensation; measured phase margin exceeds 60° at gains from 0.1× to 100× with 2 kΩ load and 100 pF parasitic capacitance.
