Product details
Overview
TS461CLT from STMicroelectronics is a single-channel rail-to-rail output operational amplifier optimized for low-voltage, low-noise audio signal conditioning. It operates from 2.7 V to 10 V (±1.35 V to ±5 V), 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 - deployed in microphone pre-amplifiers and portable multimedia devices.
For engineers reviewing the TS461CLT datasheet, TS461CLT pinout, TS461CLT application, or TS461CLT equivalent, key selection criteria include rail-to-rail output swing under low supply voltage, input offset voltage drift ≤5 µV/°C, thermal resistance of 250 °C/W in SOT23-5, and compatibility with battery-powered audio front-ends requiring <2.8 mA per amplifier quiescent current.
Technical Context
The TS461CLT employs a CMOS input stage enabling low input bias current (200–1000 nA) and high common-mode rejection (60–85 dB), paired with a class-AB output stage supporting rail-to-rail swing into 2 kΩ loads. Its 12 MHz gain-bandwidth product and 4 V/µs slew rate support wideband audio amplification without phase distortion.
Designed for single-supply or split-supply operation, it maintains stable performance across -20 °C to +70 °C ambient temperature, with input common-mode range extending from VDD +1.15 V to VCC –1.15 V - critical for DC-coupled microphone biasing and line-level signal buffering in compact portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 10 V - supports direct integration into 3.3 V or 5 V battery-powered audio subsystems without LDO regulation. |
| Output Swing | ±2.4 V at ±2.5 V supply - enables full dynamic range utilization in low-voltage recording paths with minimal headroom loss. |
| Input Noise | 4 nV/√Hz at 100 kHz - preserves SNR in mic preamp stages where gain >40 dB is applied before ADC sampling. |
| THD | 0.003 % at 1 kHz, AV = -1, RL = 10 kΩ - meets CD-quality audio fidelity requirements for consumer playback equipment. |
| Quiescent Current | 2.8 mA typical per amplifier - balances power efficiency and bandwidth for always-on audio monitoring circuits. |
| Gain-Bandwidth | 12 MHz - ensures flat frequency response up to 20 kHz with ≥60° phase margin into capacitive loads ≤100 pF. |
| Slew Rate | 4 V/µs - prevents slew-induced distortion on transient-rich audio signals such as drum transients or percussive speech peaks. |
Pinout & Package
SOT23-5 micropackage (ECOPACK® compliant), 2.9 mm × 2.8 mm footprint, 1.45 mm max height, thermal resistance RthJA = 250 °C/W - suited for space-constrained PCB layouts in handheld audio devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input | Accepts feedback network connection; high impedance (>1012 Ω) minimizes loading on preceding stage. |
| 2 | Non-inverting Input | DC-biased node for single-supply operation; common-mode range extends within 1.15 V of rails. |
| 3 | Output | Rail-to-rail capable output driving 2 kΩ load to ±2.4 V with <1 mV saturation error. |
| 4 | VDD (Negative Supply) | Connects to ground or negative rail; enables true dual-supply operation down to ±1.35 V. |
| 5 | VCC (Positive Supply) | Accepts 2.7–10 V input; internal ESD protection rated to 2 kV HBM ensures robustness during board assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >96 % of full supply range at ±2.5 V, enabling maximum signal amplitude without clipping in 3.3 V systems. |
| Low input voltage noise | 4 nV/√Hz allows clean amplification of µV-level microphone signals without degrading system SNR below 95 dB(A). |
| Low total harmonic distortion | 0.003 % THD ensures transparent audio reproduction in CD players and sound cards meeting IEC 60268-3 Class D. |
| Wide supply range | Operates from 2.7 V to 10 V - eliminates need for separate analog supply rails in mixed-signal portable designs. |
| Thermal stability | Input offset drift ≤5 µV/°C maintains DC accuracy over industrial temperature range without recalibration. |
Applications
| Microphone Pre-amplifier | Sound Card Line Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | Lower GBW (6.4 MHz), higher input bias current (1 pA typ), same SOT23-5 package. | Less suitable for >10 kHz closed-loop bandwidth; better for ultra-low-power sensor interfaces than audio. | Select when supply current <1.5 mA is mandatory and audio bandwidth ≤5 kHz suffices. |
| MCP6001T-E/OT | Higher THD (0.01 %), lower slew rate (0.6 V/µs), wider VCC range (1.8–6.0 V). | Acceptable for voice-grade but not CD-quality playback; limited by slew-induced distortion on fast transients. | Select for cost-sensitive, non-audio applications like battery monitoring or simple comparators with rail-to-rail output. |
Compared with TLV2461IDBVR and MCP6001T-E/OT, the TS461CLT uniquely combines 12 MHz GBW, 4 V/µs slew rate, and 0.003 % THD in SOT23-5 - making it the only option among the three qualified for CD-player-grade audio output stages requiring simultaneous bandwidth, fidelity, and space efficiency.

FAQ
What is the maximum output current capability of the TS461CLT?
The TS461CLT is not characterized for short-circuit output current in the datasheet. Its output stage is designed to drive 2 kΩ loads with ±2.4 V swing at ±2.5 V supply. For heavier loads, output voltage swing compresses due to internal current limiting - typical output current remains below ±20 mA to maintain specified THD and slew rate performance.
Can the TS461CLT operate with a single 3.3 V supply?
Yes. The TS461CLT supports single-supply operation from 2.7 V to 10 V. With VCC = 3.3 V and VDD = 0 V, its input common-mode range spans 1.15 V to 2.15 V, and output swings from 0.1 V to 3.2 V - sufficient for AC-coupled microphone pre-amplifier or line-driver configurations using appropriate DC biasing networks.
Does the TS461CLT include ESD protection on all pins?
Yes. The TS461CLT features integrated ESD protection rated to 2 kV HBM (Human Body Model), 200 V MM (Machine Model), and 1.5 kV CDM (Charged Device Model) on all pins - verified per JEDEC JS-001, JS-002, and JESD22-C101 standards - ensuring robust handling during PCB assembly and field operation.
Is the TS461CLT pin-compatible with other SOT23-5 op-amps like the MCP6001?
No. While both use SOT23-5 packages, pin assignments differ: TS461CLT uses Pin 1 = Inverting Input, Pin 2 = Non-inverting Input, Pin 3 = Output, Pin 4 = VDD, Pin 5 = VCC; MCP6001 uses Pin 1 = Output, Pin 2 = Inverting Input, Pin 3 = Non-inverting Input, Pin 4 = VDD, Pin 5 = VCC - direct replacement requires PCB layout revision.
