Product details
Overview
TSV852IQ2T 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 TSV852IQ2T datasheet, TSV852IQ2T pinout, TSV852IQ2T application, or TSV852IQ2T equivalent, this page provides verified electrical specifications, dual op-amp shutdown timing (300 ns turn-on), SC70-5 package mapping, automotive-grade temperature validation, and real-world use cases in battery-powered sensor interfaces and medical front-ends.
Technical Context
The TSV852IQ2T integrates two independent high-accuracy amplifiers sharing a common shutdown control (SHDN) pin, enabling synchronized power gating. Its input stage supports rail-to-rail common-mode range (VCC– – 0.2 V to VCC+ – 1 V) and features enhanced ESD tolerance (4 kV HBM on signal pins, 3.5 kV on SHDN).
Each amplifier achieves 1.3 MHz GBP with 0.6–0.7 V/µs slew rate, 70–75 dB CMRR, and 72–79 dB PSRR - validated at both 2.7 V and 5 V supplies. Shutdown mode reduces total quiescent current to ≤50 nA per channel while placing outputs in high-impedance state.
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 (3.0–3.7 V) or 3.3 V/5 V rails without level shifting. |
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffer and active filter designs up to ~100 kHz with phase margin ≥60°. |
| Input Offset Voltage | 0.8 mV max at 25 °C - eliminates need for external trimming in 12-bit ADC front-ends with ±1 LSB error budget. |
| Quiescent Current | 180 µA per channel max at 5 V - extends battery life in always-on sensor nodes (e.g., >5 years on CR2032 at 10 µA avg). |
| Shutdown Current | 50 nA max per channel - reduces system standby power by >3,500× versus active mode, critical for automotive sleep modes. |
| Rail-to-Rail Output Swing | Within 100 mV of rails (RL = 10 kΩ) - maximizes dynamic range when interfacing with 3.3 V SAR ADCs or low-voltage microcontrollers. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive applications and industrial edge sensors without derating. |
Pinout & Package
TSV852IQ2T is housed in a 5-pin SC70-5 (SOT323-5) package - ultra-compact (2.0 × 1.25 × 0.9 mm), surface-mount, lead-free, ECOPACK® compliant. Pin 1 is marked via dot; pin 1 = IN+, pin 2 = IN−, pin 3 = OUT, pin 4 = VCC−, pin 5 = VCC+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance node (Iib ≤ 60 nA) accepting signals down to VCC− – 0.2 V; requires matched trace routing for noise immunity. |
| 2 | Non-inverting Input (Channel 1) | Same common-mode range as Pin 1; differential input voltage limited to ±VCC - critical for overvoltage protection design. |
| 3 | Output (Channel 1) | Rail-to-rail capable (100 mV headroom @ 10 kΩ); sinks/source up to 43 mA - drives LEDs, MOSFET gates, or ADC reference buffers directly. |
| 4 | VCC− (Ground) | Power return path; must be connected to low-impedance ground plane; decoupling capacitor (10 nF) required within 2 mm. |
| 5 | VCC+ | Positive supply input (2.3–5.5 V); accepts ceramic bypass cap; shared with Channel 2 - no separate supply pins. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown | 50 nA max ICC per channel with SHDN pulled to VCC− - enables microcontroller-controlled wake-up in energy-harvesting systems. |
| Automotive qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C) - certified for engine control modules, body electronics, and ADAS sensor signal chains. |
| Enhanced input accuracy | 0.8 mV max Vio and 1 μV/°C drift - reduces calibration frequency in medical pulse oximeters and industrial thermocouple amplifiers. |
| Rail-to-rail output | 100 mV max saturation voltage at 10 kΩ load - preserves full-scale resolution when driving 12-bit ADCs with 3.3 V reference. |
| High ESD robustness | 4 kV HBM on IN+/IN−/OUT; 3.5 kV on SHDN - eliminates need for external TVS diodes in handheld diagnostic tools. |

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 | No shutdown pin; SO8 package (larger footprint, higher thermal resistance: 125 °C/W vs. SC70-5's 205 °C/W) | Lacks power-gating capability; suited for fixed-supply systems where continuous operation is acceptable | Select when board space permits SO8 and shutdown is unnecessary - simplifies layout and reduces BOM count. |
| MCP6022-E/SN | Higher supply current (1 mA/ch), no automotive qualification, 10 µV typical Vio (lower offset but not guaranteed max) | Not rated for >85 °C ambient; unsuitable for under-hood or industrial high-temp deployments | Choose only for commercial-grade, room-temperature applications demanding lower offset - avoid in automotive or extended-temp designs. |
Compared with TSV852IST, TSV852IQ2T saves 2.8 mm² PCB area and adds shutdown control; versus MCP6022-E/SN, it guarantees 125 °C operation and 50 nA shutdown current - making it the sole choice for AEC-Q100-compliant, space-constrained, battery-sensitive systems.

FAQ
What is the maximum allowable supply voltage for TSV852IQ2T?
The absolute maximum supply voltage is 6 V, but the recommended operating range is strictly 2.3 V to 5.5 V per the datasheet. Exceeding 5.5 V risks permanent damage, even momentarily, due to internal junction limits. Operation at 6 V is prohibited in production designs.
Can the shutdown pin be left unconnected?
No - the SHDN pin must never float. It must be actively driven to either VCC+ (to enable) or VCC− (to disable). Leaving it unconnected causes undefined output states and potential shoot-through current, violating functional safety requirements in automotive applications.
Does TSV852IQ2T support single-supply operation with input signals at ground?
Yes. Its input common-mode range extends to VCC− – 0.2 V, allowing direct interface with 0 V-referenced sensors (e.g., thermistors, strain gauges) when VCC− is grounded - a key enabler for single-supply industrial sensing.
Is the SC70-5 package compatible with standard reflow profiles?
Yes - TSV852IQ2T's SC70-5 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 10–30 sec above 217 °C), with no special pre-bake required for dry-packed reels.
