Product details
Overview
TSV852AIST from STMicroelectronics is a dual-channel, rail-to-rail output, low-power operational amplifier with shutdown functionality, designed for precision signal conditioning in space-constrained automotive and portable systems. It delivers 1.3 MHz gain bandwidth, 0.8 mV max input offset voltage at 25 °C, 180 µA max supply current per channel at 5 V, and operates from 2.3 V to 5.5 V across –40 °C to +125 °C.
For engineers reviewing the TSV852AIST datasheet, TSV852AIST pinout, TSV852AIST application, or TSV852AIST equivalent, this page provides verified electrical parameters, validated dual-opamp shutdown behavior, package-specific terminal mapping for SO8, and application-specific design value for battery-powered sensor front-ends, automotive body control modules, and medical wearable signal chains.
Technical Context
The TSV852AIST integrates two independent op-amps with individual shutdown control (SHDN1/SHDN2), enabling selective channel disablement without affecting the other. Its input stage supports rail-to-rail common-mode range (VCC− − 0.2 V to VCC+ − 1 V) and rail-to-rail output swing (within 100 mV of rails at 10 kΩ load).
It features enhanced DC accuracy via 0.8 mV max Vio at 25 °C and 2 µV/°C max drift over –40 °C to +125 °C, combined with 72 dB min CMRR and 72 dB min SVR at 5 V, making it suitable for high-precision, low-voltage analog sensing where calibration overhead must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - enables direct operation from single-cell Li-ion or 3.3 V/5 V rails without LDO pre-regulation. |
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffer and active filter designs up to ~100 kHz with adequate phase margin. |
| Input Offset Voltage | 0.8 mV max at 25 °C - reduces initial error in sensor amplification, minimizing need for system-level trimming. |
| Supply Current per Channel | 180 µA max at 5 V - extends battery life in always-on monitoring nodes (e.g., tire pressure sensors, ECG leads). |
| Shutdown Current | 50 nA max per channel - cuts quiescent power by >3500×, critical for intermittent-sampling architectures. |
| Rail-to-Rail Output | VOL ≤ 180 mV, VOH ≤ 100 mV at 10 kΩ - maximizes dynamic range in low-voltage ADC interfaces (e.g., 12-bit SAR with 3.3 V reference). |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive applications and industrial edge sensors without derating. |
Pinout & Package
TSV852AIST is packaged in an 8-pin SO8 (Small Outline Integrated Circuit) with ECOPACK® compliance. Pin functions are defined per Figure 1 (SO8 top view) in ST's DocID022468 Rev 4.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1+ | Non-inverting input of Channel 1 - accepts signals down to VCC− − 0.2 V, enabling ground-referenced sensor interfacing. |
| 2 | In1− | Inverting input of Channel 1 - used for closed-loop feedback or differential input configuration. |
| 3 | Out1 | Output of Channel 1 - rail-to-rail swing supports full utilization of downstream ADC input range. |
| 4 | VCC− | Negative supply rail - tied to GND in single-supply configurations; required for proper biasing of input stage. |
| 5 | VCC+ | Positive supply rail - accepts 2.3–5.5 V; decoupling capacitor (≥10 nF) must be placed adjacent to this pin. |
| 6 | Out2 | Output of Channel 2 - independently controllable; shares no internal coupling with Out1. |
| 7 | In2− | Inverting input of Channel 2 - supports dual-sensor readout (e.g., temperature + voltage monitoring) on one die. |
| 8 | In2+ | Non-inverting input of Channel 2 - identical input range and ESD tolerance (4 kV HBM) as In1+. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | Reduces per-channel ICC to ≤50 nA, enabling microamp-level system sleep states without external MOSFET switches. |
| Enhanced input offset voltage | 0.8 mV max at 25 °C (vs. 4 mV for standard TSV852) - improves DC accuracy in strain gauge or thermistor amplifiers. |
| Automotive qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C) - eliminates requalification effort for body electronics and ADAS sub-modules. |
| Rail-to-rail input and output | Supports single-supply operation with full signal swing from near-GND to near-VCC - simplifies PCB layout and reduces BOM count. |
| High ESD tolerance | 4 kV HBM on all pins except SHDN (3.5 kV), ensuring robustness during board handling and in-cabin deployment. |
Applications
| Automotive Body Control Unit | Portable Medical Sensor Node |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV852IST | Standard Vio grade (4 mV max vs. 0.8 mV); same shutdown, GBW, and supply specs. | Lacks enhanced DC accuracy - requires calibration in precision sensor paths but costs less in cost-sensitive lighting controls. | Select when offset drift budget allows >2× higher initial error and total BOM cost is prioritized over calibration labor. |
| LMV822IDR | Higher GBP (5.5 MHz), wider supply (2.7–5.5 V), no shutdown; 1.5 mV Vio max; SO8 package. | Unsuitable for ultra-low-power sleep modes; better for higher-frequency active filters or fast-settling comparators. | Choose when bandwidth >2 MHz is mandatory and shutdown is handled externally via power gating. |
Compared with TSV852AIST, TSV852IST trades 5× lower offset for lower cost in non-critical apps, while LMV822IDR offers 4× more bandwidth at the expense of shutdown capability and higher quiescent current - making TSV852AIST optimal for battery-limited, precision, automotive-grade dual-channel signal chains.

FAQ
What is the maximum allowable supply voltage for TSV852AIST?
The absolute maximum supply voltage is 6 V, but the recommended operating range is 2.3 V to 5.5 V. Operation above 5.5 V risks permanent damage, while below 2.3 V may cause loss of rail-to-rail output swing and increased input bias current. Electrical characteristics are fully specified at 2.7 V and 5 V.
How does the shutdown pin function, and what logic levels activate it?
The SHDN pin (Pin 8 in SO8) enables or disables each amplifier independently: pulling SHDN to VCC+ (VIH ≥ VCC− + 0.5 V) enables the channel; pulling it to VCC− (VIL ≤ 0.5 V) places the output in high-impedance state and reduces supply current to ≤50 nA. The pin must never float and requires a pull-up or pull-down resistor.
Can TSV852AIST drive a 2 kΩ load while maintaining rail-to-rail output?
Yes, but with reduced swing margin: at 2 kΩ load, VOL is ≤400 mV and VOH is ≤300 mV (over –40 °C to +125 °C). For full rail-to-rail performance (≤100 mV saturation), use ≥10 kΩ loads. Driving 2 kΩ is valid for applications accepting ~300 mV headroom, such as driving ADC reference buffers with internal gain.
Is TSV852AIST pin-compatible with standard SO8 dual op-amps like LM358?
No - TSV852AIST uses non-standard SO8 pinout: Pin 1 = In1+, Pin 2 = In1−, Pin 3 = Out1, Pin 4 = VCC−, Pin 5 = VCC+, Pin 6 = Out2, Pin 7 = In2−, Pin 8 = In2+. LM358 uses Pin 1 = Out1, Pin 2 = In1−, Pin 3 = In1+, Pin 4 = VCC−, Pin 5 = In2+, Pin 6 = In2−, Pin 7 = Out2, Pin 8 = VCC+. Direct replacement requires PCB redesign.
