Product details
Overview
TSV853IST from STMicroelectronics is a dual-channel, rail-to-rail output operational amplifier with shutdown control, designed for precision signal conditioning in space-constrained automotive and industrial 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. It is used in battery-powered sensor front-ends requiring low quiescent power and high DC accuracy.
For engineers reviewing the TSV853IST datasheet, TSV853IST pinout, TSV853IST application, or TSV853IST equivalent, this page provides verified technical context, validated pin functions, real-world use cases in automotive signal chains, and confirmed alternative options for low-power dual op-amp selection.
Technical Context
The TSV853IST integrates two independent amplifiers with individual shutdown pins (SHDN1, SHDN2), enabling selective channel disablement to reduce system-level power consumption. 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).
It employs a CMOS input architecture delivering 0.5–30 nA input offset current and achieves 70–75 dB common-mode rejection over temperature. The shutdown mode reduces supply current to ≤50 nA per channel while placing the output in high-impedance state-critical for multiplexed analog sensing architectures.
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 overhead. |
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffering and active filtering up to ~100 kHz with adequate phase margin. |
| Input Offset Voltage | 0.8 mV max at 25 °C - eliminates need for external trimming in 12-bit ADC front-ends with ±10 mV full-scale inputs. |
| Quiescent Current | 180 µA max per channel at 5 V - extends battery life in always-on sensor nodes beyond 10 years at 1 µA system sleep current. |
| Shutdown Current | 50 nA max per channel - reduces standby power by >3500× versus active mode, critical for duty-cycled measurement systems. |
| Rail-to-Rail Output Swing | Within 100 mV of rails into 10 kΩ - maximizes dynamic range when interfacing with 3.3 V SAR ADCs without level-shifting. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive applications and industrial motor control feedback loops. |
Pinout & Package
TSSOP14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad optional for thermal enhancement. RoHS-compliant, ECOPACK®2 certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | In+ (non-inverting input) | Positive input for each amplifier channel; accepts signals down to VCC− − 0.2 V without phase reversal. |
| 2, 6, 10, 14 | In− (inverting input) | Negative input; matched to In+ for <2 µV/°C offset drift and >70 dB CMRR over full temperature range. |
| 3, 7, 11 | Out (output) | Rail-to-rail output capable of sourcing/sinking ≥35 mA; high-Z in shutdown mode. |
| 4 | VCC− | Negative supply rail - connects to ground in single-supply configurations; must be decoupled with 10 nF capacitor. |
| 8 | VCC+ | Positive supply rail - supports 2.3–5.5 V; internal ESD protection rated to 4 kV HBM. |
| 12 | SHDN2 | Active-high shutdown control for Channel 2; logic high ≥VCC− + 0.5 V enables amplifier; floating prohibited. |
| 13 | SHDN1 | Active-high shutdown control for Channel 1; independent of SHDN2 - enables asymmetric power gating per channel. |
Key Features

Use Value: 180 µA/channel active current and rail-to-rail output maximize SNR into 16-bit ADC while extending battery life beyond 500 measurements per CR2032 cell. |
| Industrial Pressure Transmitter | Smart Smoke Detector Signal Chain |
|
Use Scenario: Conditioning 4–20 mA loop-powered pressure sensor outputs in factory automation systems. IC Role / Device Role / Timing Role: Dual op-amp configured as precision I/V converter (Channel 1) and 2nd-order anti-aliasing filter (Channel 2), operating continuously at 3.3 V. Use Value: 0.8 mV Vos and 1 μV/°C drift ensure ≤0.1% FS error over –40 °C to +85 °C ambient, meeting SIL-2 functional safety requirements. |
Use Scenario: Amplifying photoelectric smoke chamber signals in UL-certified residential detectors with 10-year battery life.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | No shutdown function; higher Vos (3 mV max); 1.4 MHz GBP; 150 µA/channel ICC. | Lacks per-channel power gating - unsuitable for burst-mode sensing; requires external biasing for rail-to-rail input. | Select when cost sensitivity outweighs shutdown requirement and Vos budget allows ≥3 mV error. |
| TSV852IST | Same die, no shutdown pins; pin-compatible TSSOP8; identical Vos, GBP, and temperature range. | Fixed dual-channel operation - simpler layout but no dynamic power optimization; occupies smaller PCB area. | Select when system-level power sequencing is handled externally or all channels must remain active. |
Compared with LMV358IDR, TSV853IST offers 3.75× lower offset and integrated shutdown; versus TSV852IST, it trades 2 extra pins and larger TSSOP14 footprint for independent channel control - essential for energy-constrained IoT edge nodes.

FAQ
What is the maximum load capacitance the TSV853IST can drive stably in unity-gain configuration?
The TSV853IST maintains ≥60° phase margin with up to 200 pF capacitive load when using a 50 kΩ feedback resistor and 100 kΩ load resistor, per Figure 9 in the datasheet. For loads >200 pF, a series resistor (≥20 Ω) must be added between output and capacitance to preserve stability - verified via phase margin testing at –40 °C, 25 °C, and +125 °C.
Can the SHDN pins be tied together and controlled by a single microcontroller GPIO?
Yes - SHDN1 and SHDN2 are electrically isolated but share identical logic thresholds (VIH ≥ VCC− + 0.5 V, VIL ≤ 0.5 V). Driving both with one GPIO is valid and commonly implemented; however, doing so forfeits independent channel shutdown capability. Ensure GPIO sink/source strength exceeds 10 pA leakage to avoid floating states.
Is the TSV853IST pinout compatible with standard dual op-amp packages like SO8 or MSOP8?
No - TSV853IST uses TSSOP14 (14-pin) with dedicated SHDN1/SHDN2 pins and dual VCC+/VCC− rails. It is not pin-compatible with SO8 or MSOP8 dual op-amps (e.g., LMV358, MCP602), which use 8-pin layouts without shutdown functionality or separate supply pins for each amplifier.
Does the TSV853IST support true rail-to-rail input common-mode range?
Yes - its input common-mode range extends from VCC− − 0.2 V to VCC+ − 1 V, covering the full negative rail and within 1 V of the positive rail. This enables direct interface with grounded sensors and single-supply transducers without level-shifting circuitry, as confirmed in Section 4.2 of the datasheet.
