Product details
Overview
TSV853AIST from STMicroelectronics is a dual-channel, rail-to-rail output operational amplifier with shutdown functionality, designed for precision signal conditioning in space-constrained, low-power 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 front-ends and portable medical monitors.
For engineers reviewing the TSV853AIST datasheet, TSV853AIST pinout, TSV853AIST application, or TSV853AIST equivalent, key selection criteria include shutdown-enabled power gating (50 nA max), enhanced DC accuracy versus LMV358, rail-to-rail output swing under 200 mV from rails, and AEC-Q100 Grade 1 qualification for automotive signal chains.
Technical Context
The TSV853AIST integrates two independent high-accuracy op-amps with dedicated SHDN1/SHDN2 control pins, enabling per-channel power management. Its input stage supports common-mode voltage down to VCC– – 0.2 V and up to VCC+ – 1 V, with no phase reversal - critical for single-supply transducer interfacing.
Each amplifier features 1.3 MHz GBP, 0.6–0.7 V/µs slew rate, and 70–75 dB CMRR at 25 °C, optimized for stable unity-gain operation with capacitive loads up to 200 pF. Shutdown mode reduces supply current to ≤50 nA while placing the output in high-impedance state - verified per Table 5 and Section 4.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - enables direct interface with Li-ion battery (3.0–4.2 V) and 3.3 V/5 V logic without level shifting |
| Input Offset Voltage (max) | 0.8 mV at 25 °C - ensures ≤0.8 LSB error in 12-bit ADC front-end with 2 V full-scale range |
| Gain Bandwidth Product | 1.3 MHz - supports closed-loop bandwidth >100 kHz in gain-of-10 configurations for active filtering |
| Shutdown Current (max) | 50 nA per channel at 25 °C - extends battery life by >100× vs. active mode in intermittent-sampling systems |
| Rail-to-Rail Output Swing | ≤100 mV from rails (RL = 10 kΩ) - maximizes dynamic range in single-supply 3.3 V data acquisition |
| Operating Temperature | –40 °C to +125 °C - validated for under-hood automotive environments and industrial motor control enclosures |
| ESD Robustness | 4 kV HBM (non-SHDN pins), 3.5 kV HBM (SHDN pin) - reduces field failure risk in manual handling and PCB assembly |
Pinout & Package
TSSOP14 package: 4.4 mm × 5.0 mm × 1.2 mm body, 0.65 mm pitch, exposed pad optional (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | In+ (non-inverting input) | High-impedance node (Iib ≤ 60 nA) for precision voltage sensing or thermistor biasing |
| 2, 6, 10, 14 | In– (inverting input) | Differential input pair node; supports feedback networks up to 10 MΩ without significant drift |
| 3, 7, 11 | Out (output) | Rail-to-rail capable; drives ≥10 kΩ load to within 100 mV of VCC+/VCC– at 25 °C |
| 4 | VCC– (negative supply) | Ground reference for single-supply operation; must be decoupled with 10 nF capacitor |
| 8 | VCC+ (positive supply) | Primary power rail; accepts 2.3–5.5 V; requires local 10 nF ceramic decoupling |
| 12 | SHDN2 | Active-high digital control: pulls high ≥VCC– + 0.5 V to enable Channel 2; ≤0.5 V disables |
| 11 | SHDN1 | Active-high digital control: identical timing and threshold behavior as SHDN2 for Channel 1 |
Key Features
| Feature | Design Value |
|---|---|
| Per-channel shutdown control | Independent SHDN1/SHDN2 pins allow selective power-down of one op-amp while the other remains active - reducing system-level quiescent current without redesign |
| Automotive-grade qualification | AEC-Q100 Grade 1 certified (–40 °C to +125 °C) - eliminates requalification effort for engine control, ADAS sensor modules, and body electronics |
| Enhanced input offset voltage | 0.8 mV max (vs. 3–7 mV for LMV358) - lowers calibration burden in factory-trimmed pressure or current-sense circuits |
| Low-noise rail-to-rail output | 30 nV/√Hz input voltage noise at 1 kHz, with output swing to within 100 mV of rails - preserves SNR in battery-powered ECG front-ends |
| Robust input common-mode range | VICM extends to VCC– – 0.2 V - enables direct connection to 0 V-referenced sensors (e.g., bridge transducers, RTDs) without level-shifting circuitry |
Applications
| Automotive Cabin Pressure Sensing | Portable Blood Glucose Monitor |
|---|---|
|
Use Scenario: Amplifying millivolt-level output from piezoresistive cabin pressure sensors in HVAC control units. IC Role / Device Role / Timing Role: Dual-channel signal conditioner: Channel 1 buffers sensor excitation; Channel 2 amplifies differential output with 100× gain. Use Value: 0.8 mV Vio ensures <±0.1% full-scale error over temperature; shutdown mode cuts idle current to 50 nA during sleep cycles between readings. |
Use Scenario: Signal conditioning for amperometric glucose test strip current (1–100 nA) in handheld meters. IC Role / Device Role / Timing Role: Transimpedance amplifier (TIA) with programmable gain; shutdown disables TIA between strip insertion and measurement. Use Value: 60 nA Iib minimizes input current error; rail-to-rail output drives 12-bit SAR ADC directly from 3.3 V supply. |
| Industrial Motor Current Monitoring | Smart Smoke Detector Analog Front-End |
|
Use Scenario: Isolated current sensing using shunt resistor and optocoupler feedback in variable-frequency drives. IC Role / Device Role / Timing Role: Precision difference amplifier rejecting common-mode noise on 48 V DC bus; second channel filters PWM ripple. Use Value: 75 dB CMRR rejects 100 kHz switching noise; 1.3 MHz GBP supports >50 kHz closed-loop bandwidth for fast fault detection. |
Use Scenario: Amplifying weak ionization chamber current (sub-pA) in photoelectric smoke detectors with ultra-low standby power. IC Role / Device Role / Timing Role: Low-bias-current preamplifier with shutdown activated during 60-second alarm silence intervals. Use Value: 0.5 nA Iio typ and 50 nA shutdown current extend 10-year battery life; AEC-Q100 qualification ensures reliability in fire-safety-critical systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | Higher Vio (3 mV max), no shutdown, wider supply (2.7–5.5 V), lower GBP (1 MHz) | Lacks per-channel power control; unsuitable for intermittent-sampling architectures requiring microamp-level sleep current | Select when cost sensitivity outweighs shutdown need and Vio tolerance >3 mV is acceptable |
| TSV852AIST | Same specs but no shutdown pins; TSSOP8 package (fewer pins, no SHDN1/SHDN2) | Requires external FET or power switch for channel disable; increases BOM count and board area | Select when both channels always operate concurrently and space constraints favor smaller 8-pin footprint |
Compared with LMV358QDRQ1 and TSV852AIST, the TSV853AIST uniquely delivers sub-1 mV offset, integrated dual shutdown, and AEC-Q100 qualification in a single 14-pin package - simplifying design for automotive and portable medical systems requiring guaranteed low-power precision.

FAQ
What is the maximum allowable capacitive load for stable operation of TSV853AIST?
The TSV853AIST maintains ≥60° phase margin with capacitive loads up to 200 pF when driving a 50 kΩ resistive load (Figure 9). For loads >200 pF, external isolation resistance (≥100 Ω) is required to prevent peaking or oscillation - confirmed in Figure 10 and Figure 11 across –40 °C to +125 °C.
Can the SHDN pins be left unconnected or tied to ground through a pull-down resistor?
No. The SHDN pins must never float: they must be actively driven to VCC+ (to enable) or VCC– (to disable), or tied directly to VCC+ or VCC– with zero-ohm connections. A pull-down resistor risks violating the VIL specification (≤0.5 V) under leakage or noise, causing unintended shutdown - per Section 4.7 and Table 5.
Does TSV853AIST support true rail-to-rail input common-mode range?
No. The input common-mode range is VCC– – 0.2 V to VCC+ – 1 V (Table 3), meaning it includes ground but does not reach VCC+. This allows direct interfacing with 0 V-referenced sensors but requires level-shifting for signals near VCC+ - unlike full rail-to-rail input op-amps.
How does the 1.3 MHz GBP translate to usable closed-loop bandwidth in a gain-of-10 configuration?
At gain-of-10, the small-signal closed-loop bandwidth is approximately 130 kHz (GBP ÷ noise gain), verified in Figure 12 for CL ≤ 200 pF. This supports anti-aliasing filter design for 100 kSPS ADCs and real-time response in motor current loop compensation - consistent across temperature per AC characterization in Tables 4 and 6.
