Product details
Overview
TSV852AIDT from STMicroelectronics is a dual-channel, rail-to-rail output operational amplifier with shutdown functionality, designed for precision signal conditioning in low-voltage 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 - enabling use in automotive sensor interfaces and portable medical monitors.
For engineers reviewing the TSV852AIDT datasheet, TSV852AIDT pinout, TSV852AIDT application, or TSV852AIDT equivalent, key selection criteria include its shutdown-enabled power efficiency (50 nA max), enhanced DC accuracy versus LMV358, rail-to-rail output swing under 2 kΩ load, and AEC-Q100 qualification for automotive signal chains.
Technical Context
The TSV852AIDT integrates two independent op-amps in a single SO-8 package, each featuring an active high shutdown control (SHDN pin) that places the output in high-impedance state and reduces total supply current to ≤50 nA. Its input stage supports common-mode voltage down to VCC– – 0.2 V and up to VCC+ – 1 V, with no phase reversal.
It employs a CMOS input stage delivering 0.5–30 nA input offset current and achieves 70–75 dB common-mode rejection ratio (CMRR) and 72–79 dB supply voltage rejection ratio (SVRR) over temperature, supporting stable operation in noisy automotive and industrial environments without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.3 MHz - enables stable unity-gain buffer or 10× inverting amplifier up to ~130 kHz with adequate phase margin. |
| Input Offset Voltage (max) | 0.8 mV at 25 °C - supports 12-bit ADC interfacing without calibration in battery-powered sensor nodes. |
| Supply Current (per channel) | 180 µA max at 5 V - extends runtime in coin-cell–powered devices beyond 10 years at 1 Hz sampling. |
| Shutdown Current | 50 nA max at 25 °C - reduces system standby power by >99.9% versus active mode. |
| Rail-to-Rail Output Swing | ≤100 mV from rails into 10 kΩ - preserves dynamic range in 3.3 V microcontroller ADC front-ends. |
| Operating Voltage Range | 2.3 V to 5.5 V - compatible with Li-ion, Li-Po, and dual-cell alkaline supplies without LDO pre-regulation. |
| Temperature Range | –40 °C to +125 °C - qualified for engine bay and transmission control unit deployment. |
Pinout & Package
TSV852AIDT is housed in an SO-8 (Small Outline Integrated Circuit, 8-pin) package with exposed pad option (ECOPACK® compliant). Pin 1 is marked via notch or dot; device orientation follows JEDEC MS-012 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts differential signal reference; high-impedance CMOS input (Iib ≤ 60 nA). |
| 2 | Non-inverting Input (Channel 1) | Connects to sensor bridge or reference divider; supports rail-to-rail common-mode range. |
| 3 | Output (Channel 1) | Delivers rail-to-rail swing; sinks/supplies ≥35 mA at 5 V for driving RC filters or ADC inputs. |
| 4 | VCC– (Ground) | Power return path; must be decoupled with 10 nF capacitor placed <1 mm from pin. |
| 5 | VCC+ (Supply) | Positive supply rail (2.3–5.5 V); connects to same net as all other VCC+ pins in multi-channel designs. |
| 6 | Non-inverting Input (Channel 2) | Independent second channel input; electrically isolated from Channel 1 except shared supply rails. |
| 7 | Inverting Input (Channel 2) | Supports dual-sensor configurations (e.g., differential thermocouple + RTD readout). |
| 8 | Shutdown (SHDN) | Active-high logic control; pulls high to enable both amplifiers; must not float. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C) - validated for under-hood ECU signal conditioning. |
| ESD tolerance | 4 kV HBM (non-SHDN pins), 3.5 kV HBM (SHDN pin) - withstands assembly handling and field transients. |
| Rail-to-rail output | 100 mV max saturation voltage into 10 kΩ - maximizes usable ADC input range in 3.3 V systems. |
| Low input bias current | 27–60 nA typ at 25 °C - minimizes error in high-impedance pH or photodiode sensor interfaces. |
| Turn-on/turn-off time | 300 ns turn-on, 20 ns turn-off - enables microsecond-scale power gating in duty-cycled sensor systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher offset (3 mV max), no shutdown, 1 MHz GBP, wider supply (2.7–5.5 V) | Lacks power-gating capability; unsuitable for ultra-low-power wake-up architectures | Select when cost sensitivity outweighs shutdown need and offset budget allows ≥3 mV error. |
| TSV852IST | Same core specs but in MiniSO-8 package (3.0 × 3.0 mm vs SO-8's 4.9 × 6.0 mm); identical pinout | Enables higher board density in space-constrained wearables or modules | Select when PCB area is constrained and thermal dissipation permits smaller package RθJA = 190 °C/W. |
Compared with LMV358IDR and TSV852IST, the TSV852AIDT uniquely combines AEC-Q100 qualification, sub-1 mV offset, and integrated shutdown in standard SO-8 - making it optimal for automotive and long-life portable designs where accuracy, reliability, and power control are jointly critical.

FAQ
What is the maximum capacitive load the TSV852AIDT can drive while maintaining stability?
The TSV852AIDT maintains ≥60° phase margin with up to 200 pF capacitive load when configured as a unity-gain buffer with 50 kΩ feedback resistor and 100 kΩ load to ground. Driving >500 pF requires isolation resistor (≥10 Ω) between output and capacitance to prevent peaking or oscillation, as verified in Figure 12 of the datasheet.
Does the SHDN pin require external pull-up or pull-down resistors?
No external resistors are required: the SHDN pin has internal logic threshold referenced to VCC– and VCC+, with VIH = VCC– + 0.5 V and VIL = 0.5 V. However, the pin must never be left floating - it must be driven actively high (to VCC+) to enable or low (to VCC–) to disable, per Section 4.7 of the datasheet.
Can the TSV852AIDT operate with a single 2.3 V supply and still achieve rail-to-rail output?
Yes - the device is fully specified down to 2.3 V supply and delivers rail-to-rail output swing (≤100 mV from rails into 10 kΩ) across the full operating temperature range. Output voltage compliance is guaranteed from VCC– + 0.01 V to VCC+ – 0.1 V at 2.3 V, enabling use with 2-cell alkaline or single LiFePO₄ batteries.
How does the input offset voltage drift behave over temperature?
Input offset voltage drift is specified as ΔVio/ΔT ≤ 1 µV/°C over –40 °C to +125 °C. At 125 °C, total offset remains ≤2 mV (vs. 0.8 mV at 25 °C), ensuring predictable error growth in high-temperature applications like transmission control modules without recalibration.
