Product details
Overview
TS462CD from STMicroelectronics is a dual rail-to-rail output operational amplifier in SO-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 TS462CD datasheet, TS462CD pinout, TS462CD application, or TS462CD equivalent, key selection criteria include rail-to-rail output swing under low supply voltage, audio-grade noise/distortion performance, dual-channel integration in SO-8, and compatibility with battery-powered microphone and line-level signal paths.
Technical Context
The TS462CD integrates two independent op-amps sharing a common supply (VCC/VDD), each with rail-to-rail output stage capable of ±2.4 V swing at ±2.5 V supply. Its input common-mode range extends from VDD +1.15 V to VCC −1.15 V, supporting single-supply or split-supply configurations up to 10 V total.
It achieves 12 MHz gain-bandwidth product and 4 V/µs slew rate with 2.8 mA per amplifier supply current. Input offset voltage is specified at 1–7 mV (max), and input bias current remains below 1 µA across −20 °C to +70 °C operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation down to 2.7 V or ±2.5 V split supply for portable audio systems. |
| Output Swing | ±2.4 V at ±2.5 V supply - enables full dynamic range utilization without clipping in 5 Vpp audio paths. |
| Input Noise Density | 4 nV/√Hz at 100 kHz - ensures minimal audible noise contribution in microphone preamp stages. |
| Total Harmonic Distortion | 0.003 % at 1 kHz, AV = −1, RL = 10 kΩ - meets CD-quality audio fidelity requirements. |
| Gain-Bandwidth Product | 12 MHz typical - sufficient for unity-gain stable audio filtering and buffering up to ~200 kHz. |
| Slew Rate | 4 V/µs - preserves transient integrity for fast-rising audio signals without slew-induced distortion. |
| Input Offset Voltage | 7 mV max - limits DC error in AC-coupled gain stages without requiring precision trimming. |
Pinout & Package
TS462CD is housed in an 8-pin SO-8 (Small Outline) plastic package with standard 1.27 mm pitch, compliant with ECOPACK environmental specifications. The package provides thermal resistance RthJA = 125 °C/W and supports reflow soldering per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance differential input node for first op-amp; referenced to common-mode voltage range. |
| 2 | Non-inverting Input (Amplifier A) | Second high-Z input for Amplifier A; used in non-inverting gain configurations or sensor interfaces. |
| 3 | Output (Amplifier A) | Rail-to-rail output capable of sourcing/sinking current into 2 kΩ load with <200 mV headroom. |
| 4 | VDD (Negative Supply) | Ground or negative rail connection; required even in single-supply mode (tied to GND). |
| 5 | VCC (Positive Supply) | Main positive supply rail; accepts 2.7–10 V or symmetric ±1.35–±5 V operation. |
| 6 | Inverting Input (Amplifier B) | Dedicated inverting input for second op-amp; electrically isolated from Amplifier A inputs. |
| 7 | Non-inverting Input (Amplifier B) | Independent non-inverting input for Amplifier B; supports dual-channel signal processing. |
| 8 | Output (Amplifier B) | Second rail-to-rail output; identical performance to Pin 3, enabling stereo or differential drive. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >95 % of supply rail-to-rail voltage range, maximizing signal headroom in low-voltage audio chains. |
| Low-noise architecture | 4 nV/√Hz input-referred noise enables clean amplification of weak microphone signals without added hiss. |
| Low-distortion signal path | 0.003 % THD ensures accurate reproduction of harmonic content in recording and playback applications. |
| Wide supply flexibility | Operates from 2.7 V single supply or ±2.5 V split supply - ideal for USB-powered or Li-ion-based portables. |
| Stable unity-gain configuration | Internally compensated for unity-gain stability; no external compensation required in standard gain stages. |
Applications
| Microphone Pre-amplifier | CD Player Audio Output Stage |
|---|---|
|
Use Scenario: Boosting low-level electret microphone output (5–10 mV) to line level (1 Vpp) before ADC sampling in portable recorders. IC Role / Device Role / Timing Role: Dual op-amp configured as low-noise inverting preamp (Channel A) and active filter buffer (Channel B). Use Value: 4 nV/√Hz noise floor preserves SNR; rail-to-rail output drives 10 kΩ ADC input without attenuation or clipping. |

IC Role / Device Role / Timing Role: Dual-channel line driver with DC-blocking capacitor and gain-of-1 configuration. Use Value: 0.003 % THD maintains CD-standard fidelity; ±2.4 V swing ensures full 5 Vpp signal compliance at 2.7 V supply. |
| Sound Card Line Input Buffer | Portable PDA Audio Mixer |
|
Use Scenario: Isolating and level-matching multiple analog line inputs (e.g., aux, mic, SPDIF DAC) on PC sound cards. IC Role / Device Role / Timing Role: Dual op-amp used as unity-gain buffer and impedance transformer between sources and codec. Use Value: High CMRR (85 dB) rejects ground-loop noise; wide 2.7–10 V supply range accommodates legacy and modern board rails. |
Use Scenario: Mixing mono microphone and stereo playback signals in handheld PDAs before headphone amplification. IC Role / Device Role / Timing Role: One amplifier sums inputs (inverting summing node), second buffers mixed output. Use Value: Low 2.8 mA per channel supply current extends battery life; SO-8 footprint fits tight PCB layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272CDR | Higher supply current (1.3 mA/ch vs. 2.8 mA/ch), lower GBW (2.2 MHz), higher input offset (2 mV typ). | Less suitable for high-fidelity audio due to higher THD (0.005 %) and lower slew rate (3.6 V/µs). | Prefer TS462CD where THD < 0.004 % and output swing > ±2.3 V at 2.5 V supply are mandatory. |
| LMV358IDR | Rail-to-rail input/output, but higher noise (16 nV/√Hz), higher THD (0.02 %), lower GBW (1 MHz). | Acceptable for cost-sensitive non-audio signal conditioning, not recommended for microphone or CD-quality paths. | Choose TS462CD when audio SNR > 95 dB and distortion-limited bandwidth > 20 kHz are required. |
Compared with TLC2272CDR and LMV358IDR, TS462CD delivers superior audio fidelity via lower noise, lower THD, and wider output swing - making it the preferred choice for battery-powered high-SNR analog front-ends where signal integrity is critical.

FAQ
Is TS462CD unity-gain stable?
Yes, TS462CD is internally compensated for unity-gain stability. It does not require external compensation components when configured with gain ≥ 1. This is confirmed in the datasheet's "Electrical Characteristics" table under "Large signal voltage gain" and application notes for audio buffer designs.
What is the maximum junction temperature for TS462CD?
The absolute maximum junction temperature for TS462CD is 150 °C, as specified in Table 1 of the DS1416 Rev 4 datasheet. At ambient temperatures up to +70 °C and SO-8 RthJA = 125 °C/W, continuous operation requires ≤ 320 mW total power dissipation (2 × 2.8 mA × 5 V).
Can TS462CD operate from a single 3.3 V supply?
Yes - TS462CD supports single-supply operation from 2.7 V to 10 V. With VCC = 3.3 V and VDD = 0 V, its common-mode input range is +1.15 V to +2.15 V, and output swings from ~100 mV to ~3.2 V, enabling use in 3.3 V systems with appropriate AC coupling or level-shifting.
Does TS462CD have ESD protection on all pins?
Yes - TS462CD features 2 kV HBM, 200 V MM, and 1.5 kV CDM ESD protection on all pins, as documented in Table 1 of the DS1416 Rev 4 datasheet. These ratings meet IEC 61000-4-2 Level 2 for system-level robustness in consumer audio equipment.
