Product details
Overview
TSV852IDT from STMicroelectronics is a dual, rail-to-rail output, low-power operational amplifier with shutdown capability, 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 across -40 °C to +125 °C.
For engineers reviewing the TSV852IDT datasheet, TSV852IDT pinout, TSV852IDT application, or TSV852IDT equivalent, this device is selected for battery-powered sensor interfaces, automotive cabin control signal chains, and medical wearable front-ends where low quiescent current, high accuracy over temperature, and shutdown-controlled power gating are critical.
Technical Context
The TSV852IDT integrates two independent amplifiers in a single SO8 package, each featuring an input common-mode range extending from VCC− − 0.2 V to VCC+ − 1 V and rail-to-rail output swing within 100 mV of both rails under 10 kΩ load. Its shutdown function disables both channels simultaneously via a dedicated SHDN pin, reducing total supply current to ≤50 nA.
It employs a CMOS input stage enabling ultra-low input bias current (≤60 nA), supports supply voltages from 2.3 V to 5.5 V, and maintains stable unity-gain operation with ≥60° phase margin up to 200 pF capacitive load-enabling direct driving of ADC inputs or RC filters without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.3 MHz - Enables stable unity-gain buffer or 10× gain amplification up to 130 kHz. |
| Input Offset Voltage (max) | 0.8 mV at 25 °C - Reduces DC error in precision sensor amplification without calibration. |
| Supply Current per Channel | 180 µA max at 5 V - Supports >1-year battery life in coin-cell–powered devices at 100 Hz sampling. |
| Shutdown Current | 50 nA max - Cuts system standby power by >99.9% when amplifiers are inactive. |
| Rail-to-Rail Output Swing | Within 100 mV of VCC+ and VCC− at 10 kΩ load - Maximizes dynamic range in 3.3 V or 5 V single-supply systems. |
| Operating Temperature Range | -40 °C to +125 °C - Qualified for under-hood automotive and industrial motor-control environments. |
| Input Common-Mode Range | VCC− − 0.2 V to VCC+ − 1 V - Accepts ground-referenced sensors and enables single-supply transimpedance configurations. |
Pinout & Package
TSV852IDT is housed in an 8-pin SO (Small Outline) package with exposed pad option (ECOPACK® compliant). Pin 1 is marked by a bevelled corner or dot; pin numbering follows standard SO8 top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low logic input; pulls amplifier into 50 nA shutdown state when tied to VCC−. |
| 2 (IN1−) | Inverting input of Channel 1 | Differential input node with 27–60 nA bias current; supports high-impedance sensor interfaces. |
| 3 (IN1+) | Non-inverting input of Channel 1 | Matches IN1− in offset and drift; enables precision instrumentation amplifier configurations. |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; also serves as shutdown logic low reference. |
| 5 (OUT1) | Output of Channel 1 | Rail-to-rail capable; drives 10 kΩ load to within 100 mV of either rail at 25 °C. |
| 6 (OUT2) | Output of Channel 2 | Independent output; shares same rail-to-rail performance and load drive capability as OUT1. |
| 7 (IN2−) | Inverting input of Channel 2 | Electrically identical to IN1−; supports dual-channel synchronous signal processing. |
| 8 (VCC+) | Positive supply rail | Accepts 2.3–5.5 V; internal regulation ensures stable operation across automotive battery transients. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | Reduces total supply current to ≤50 nA, enabling microamp-level system sleep states. |
| Enhanced input offset voltage | 0.8 mV max at 25 °C and 2 mV max over full -40 °C to +125 °C range-improves DC accuracy without trimming. |
| Rail-to-rail output stage | Delivers full 3.3 V or 5 V output swing into 10 kΩ, maximizing ADC utilization in single-supply data acquisition. |
| Automotive qualification | AEC-Q100 Grade 1 qualified (-40 °C to +125 °C), supporting deployment in body control modules and ADAS sensor nodes. |
| High ESD tolerance | 4 kV HBM (non-shutdown pins), 3.5 kV HBM (SHDN pin), and 1.3 kV CDM-reduces field failure risk in assembly and end-use. |

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 | Same silicon, SC70-8 package (smaller footprint, higher thermal resistance: 205 °C/W vs. 125 °C/W). | Limited PCB area but reduced heat dissipation margin; unsuitable for sustained >1 mA output current. | Select when board space is constrained and ambient temperature remains <85 °C. |
| LMV822IDR | Higher GBP (5.5 MHz), higher supply current (380 µA/channel), no shutdown function, wider offset range (3 mV max). | Better for AC-coupled active filtering but lacks power-gating capability and automotive temp grade. | Select when bandwidth >2 MHz is required and shutdown is not needed; verify thermal design at 125 °C. |
Compared with TSV852IDT, TSV852IST trades thermal performance for miniaturization, while LMV822IDR sacrifices low-power operation and automotive qualification for higher speed-making TSV852IDT optimal for thermally demanding, battery-sensitive automotive and industrial edge nodes.

FAQ
What is the maximum capacitive load the TSV852IDT can drive without instability?
The TSV852IDT maintains ≥60° phase margin with up to 200 pF capacitive load at unity gain when driving a 50 kΩ resistive load, as verified in Figure 9 of the datasheet. For loads >200 pF, a series resistor (≥100 Ω) between output and capacitor is recommended to preserve stability in ADC driver or filter applications.
Does the SHDN pin require a pull-up resistor, and what value is recommended?
Yes-the SHDN pin must never float. A 10 kΩ pull-up resistor to VCC+ ensures reliable enablement during power-up. The datasheet specifies VIH ≥ VCC− + 0.5 V and VIL ≤ 0.5 V, making 10 kΩ compatible with standard CMOS logic drivers and minimizing current draw in shutdown state.
Can the TSV852IDT operate with a single 2.5 V supply, and how does performance change?
Yes-it is fully specified down to 2.3 V. At 2.5 V, supply current drops to ~160 µA/channel (vs. 180 µA at 5 V), GBP remains 1.3 MHz, and rail-to-rail output swing degrades only marginally (to within 120 mV of rails at 10 kΩ), preserving usability in ultra-low-voltage energy-harvesting systems.
Is the TSV852IDT pin-compatible with legacy SO8 dual op-amps like the LM358?
No-TSV852IDT uses non-standard pinout: SHDN on Pin 1, VCC− on Pin 4, and VCC+ on Pin 8. LM358 places VCC+ on Pin 8 but has no shutdown pin and assigns IN1− to Pin 2, IN1+ to Pin 3, OUT1 to Pin 1, and VCC− to Pin 4-requiring PCB redesign for drop-in replacement.
