Product details
Overview
TS952IN from STMicroelectronics is a dual rail-to-rail input/output BiCMOS operational amplifier optimized for 3 V and 5 V single-supply operation, delivering 3 MHz gain-bandwidth product, 1 V/µs slew rate, and 0.9 mA supply current per amplifier at 3 V - used in industrial signal conditioning and portable headphone driver circuits.
For engineers reviewing the TS952IN datasheet, TS952IN pinout, TS952IN application, or TS952IN equivalent, key selection criteria include rail-to-rail I/O swing (VOL = 80 mV, VOH = 2.9 V at 3 V), ±12 V absolute max supply, -40 °C to +125 °C operating range, latch-up immunity, and SO8 package compatibility with standard PCB layouts.
Technical Context
The TS952IN implements a BiCMOS input stage enabling rail-to-rail common-mode input voltage range (VDD − 0.2 V to VCC + 0.2 V) and rail-to-rail output swing (VOL ≤ 250 mV, VOH ≥ 2.9 V at 3 V). Its unity-gain stable architecture achieves 60° phase margin with 100 pF capacitive load.
It operates across 2.7 V to 12 V supply, supports differential input voltages up to ±1 V without external limiting resistors, and maintains 80 dB supply voltage rejection ratio (SVR) and 80 dB common-mode rejection ratio (CMRR) over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - supports audio-frequency filtering and DAC buffering up to ~100 kHz closed-loop bandwidth. |
| Slew Rate | 1 V/µs - sufficient for 10 kHz full-scale sine output at 6 Vpp without distortion. |
| Input Offset Voltage | 6–8 mV (max) - suitable for medium-precision signal conditioning where <1% error budget is acceptable. |
| Supply Current per Amplifier | 0.9–1.3 mA at 3 V - enables dual op-amp operation in battery-powered devices with sub-3 mA total quiescent draw. |
| Output Voltage Swing | Rail-to-rail: VOL ≤ 250 mV, VOH ≥ 2.9 V at 3 V / RL = 600 Ω - maximizes dynamic range in low-voltage systems. |
| ESD Robustness | HBM: 2 kV - exceeds JEDEC JS-001 Class 2, supporting handling in non-ESD-controlled assembly environments. |
Pinout & Package
TS952IN is supplied in an 8-pin SOIC (SO8) package with 1.27 mm pitch, body dimensions 4.9 mm × 6.0 mm × 1.75 mm, and ECOPACK® RoHS-compliant finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Low-impedance buffered output of first amplifier; drives loads down to 600 Ω while maintaining rail-to-rail swing. |
| 2 | Inverting Input 1 | Differential input node for Amp1; accepts signals from VDD − 0.2 V to VCC + 0.2 V with 35–200 nA bias current. |
| 3 | Non-inverting Input 1 | Differential input node for Amp1; identical CMVR and bias specs as Pin 2; enables unity-gain follower configuration. |
| 4 | VCC− / GND | Negative supply terminal; referenced to system ground in single-supply operation; must be connected for proper biasing. |
| 5 | Non-inverting Input 2 | Differential input node for Amp2; electrically isolated from Amp1; shares same CMVR and noise specs. |
| 6 | Inverting Input 2 | Differential input node for Amp2; supports independent feedback networks; no crosstalk with Amp1 inputs. |
| 7 | Output 2 | Independent low-impedance output of second amplifier; fully specified for simultaneous operation with Output 1. |
| 8 | VDD / VCC+ | Positive supply terminal; accepts 2.7–12 V; internal regulation ensures stable bias under load transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 0.2 V beyond both supply rails - eliminates need for input biasing resistors in single-supply sensor interfaces. |
| Rail-to-rail output voltage swing | Delivers >95% of supply rail-to-rail span at 600 Ω load - preserves full dynamic range in low-voltage audio and DAC output stages. |
| Latch-up immunity | Rated for 200 mA injection - prevents destructive failure during power sequencing or transient overvoltage events. |
| Low-power operation | 0.9 mA per amplifier at 3 V - enables dual-channel amplification in space-constrained, thermally sensitive applications. |
| High-speed performance | 3 MHz GBW + 1 V/µs slew rate - supports active filters, anti-aliasing stages, and fast-settling buffer applications. |
Applications
| Industrial Signal Conditioning | Portable Headphone Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS952IPT | TSSOP8 package (3.0 × 3.1 mm), thinner profile (1.05 mm), higher thermal resistance (120 °C/W vs. 125 °C/W). | Better suited for high-density portable designs where board area is constrained but thermal dissipation is managed. | Select when footprint reduction outweighs SO8's superior thermal performance and legacy compatibility. |
| LMV358IDR | Lower GBW (1 MHz), higher supply current (140 µA per amp @ 5 V), no latch-up immunity rating, HBM ESD = 2 kV. | Targeted at cost-sensitive consumer electronics where speed and robustness are secondary to BOM cost. | Choose only if design tolerates reduced bandwidth, higher noise, and lacks requirement for industrial-grade reliability. |
Compared with TS952IPT, TS952IN offers better thermal management in SO8 and broader legacy PCB support; versus LMV358IDR, it delivers 3× higher speed, 6× lower quiescent current at 3 V, and guaranteed latch-up immunity for mission-critical systems.

FAQ
Is TS952IN qualified for automotive applications?
No. TS952IN is rated for industrial temperature range (−40 °C to +125 °C) but lacks AEC-Q100 qualification. For automotive use, ST offers TS952IYDT and TS952IYPT variants explicitly qualified to AEC-Q100 Grade 2 and screened per AEC-Q001/Q002.
Can TS952IN operate from a single 3.3 V supply?
Yes. TS952IN is fully specified for 2.7 V to 12 V single-supply operation. At 3.3 V, it delivers rail-to-rail input (−0.2 V to 3.5 V) and output (≤100 mV low, ≥3.2 V high at 600 Ω), with 0.95 mA supply current per amplifier and 3 MHz GBW.
What is the maximum capacitive load TS952IN can drive stably?
TS952IN is unity-gain stable with up to 100 pF capacitive load, as verified by 60° phase margin in datasheet Figure 3. Driving >100 pF requires external isolation resistor (e.g., 10–100 Ω in series) to maintain stability without oscillation.
Does TS952IN have shutdown or enable functionality?
No. TS952IN has no power-down pin or enable control. It operates continuously when powered. For applications requiring standby mode, external MOSFET-based supply gating or selection of TS952 variants with shutdown (e.g., TS952IST) is required.
