Product details
Overview
TSV854IYPT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with shutdown capability, designed for precision signal conditioning in automotive and battery-powered systems. It delivers 1.3 MHz gain bandwidth, 180 µA per channel supply current at 5 V, 0.8 mV max input offset voltage at 25 °C, and operates from 2.3 V to 5.5 V across –40 °C to +125 °C. It is used in automotive sensor front-ends requiring low-power, high-accuracy amplification with thermal robustness.
For engineers reviewing the TSV854IYPT datasheet, TSV854IYPT pinout, TSV854IYPT application, or TSV854IYPT equivalent, this page provides verified electrical specifications, SO14 package layout, shutdown timing behavior, rail-to-rail output drive capability under 2 kΩ load, and validated alternatives for automotive-grade op-amp replacement.
Technical Context
The TSV854IYPT implements a CMOS input stage enabling rail-to-rail input common-mode range (VCC− − 0.2 V to VCC+ − 1 V) and rail-to-rail output swing (within 100 mV of rails at 10 kΩ). Its shutdown function disables all four amplifiers simultaneously via a dedicated SHDN pin, reducing total supply current to ≤50 nA at 25 °C.
It features 70 dB minimum CMRR and 72 dB SVRR at 25 °C, supports unity-gain stable operation with ≥60° phase margin up to 200 pF capacitive load, and maintains 0.6–0.7 V/µs slew rate across 2.7 V–5.5 V supply. Input offset drift is limited to 1 µV/°C over –40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables single-package integration of four independent signal paths for multi-sensor conditioning. |
| Supply Voltage Range | 2.3 V to 5.5 V - supports direct connection to Li-ion battery (3.0–4.2 V) and 3.3 V/5 V logic rails without level-shifting. |
| Gain Bandwidth Product | 1.3 MHz - sufficient for anti-aliasing filters, sensor amplification, and active low-pass filtering up to ~100 kHz. |
| Input Offset Voltage | 0.8 mV max at 25 °C - enables <1% error in 100 mV full-scale medical or automotive sensor outputs without trimming. |
| Shutdown Current | 50 nA max per amplifier - extends battery life in intermittent-sampling systems (e.g., tire pressure monitors). |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive use and industrial edge nodes without derating. |
| Rail-to-Rail Output | VOL ≤ 180 mV / VOH ≤ 100 mV at 10 kΩ - maximizes dynamic range in single-supply data acquisition with 12-bit ADCs. |
Pinout & Package
TSV854IYPT is supplied in a 14-lead SOIC (SO14) package with exposed pad not present. Pin functions are defined per Figure 1 (SO14/TSSOP14) in ST's DocID022468 Rev 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | In+ (non-inverting input) | Positive input for each of four op-amps; accepts signals down to VCC− − 0.2 V with no phase reversal. |
| 2, 6, 10, 14 | In− (inverting input) | Negative input for each op-amp; matched bias current ensures low offset in transimpedance configurations. |
| 3, 7, 11, 12 | Out (output) | Rail-to-rail output capable of sourcing/sinking ≥35 mA at 5 V; drives 2 kΩ loads with <400 mV headroom. |
| 4 | VCC− (negative supply) | Ground reference for single-supply operation; also serves as logic low for SHDN pin. |
| 8 | VCC+ (positive supply) | Primary power rail; decoupling capacitor must be placed within 2 mm per Section 4.5. |
| 12 | SHDN1/2 | Shared shutdown control for Amp1 & Amp2; pulled high to enable, pulled to VCC− to disable both. |
| 13 | SHDN3/4 | Shared shutdown control for Amp3 & Amp4; independent of SHDN1/2 for partial system power gating. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | Reduces total quiescent current to ≤200 nA (4 × 50 nA) - enables microamp-level sleep states in always-on ECUs. |
| Automotive qualification | AEC-Q100 Grade 1 compliant - guaranteed operation at 125 °C ambient with 100% production test screening. |
| Enhanced ESD tolerance | 4 kV HBM on signal pins, 3.5 kV on SHDN - eliminates need for external protection in PCB-constrained automotive modules. |
| Miniaturized footprint options | Also available in TSSOP14 and MiniSO10 - reduces board area by 40% vs. standard SO14 while maintaining same pinout. |
| Stable with capacitive loads | Maintains ≥60° phase margin with up to 200 pF load - simplifies driving long traces or ADC input capacitance without isolation resistors. |
Applications
| Automotive Cabin Pressure Sensing | Portable ECG Front-End |
|---|---|
|
Use Scenario: Amplifying piezoresistive cabin pressure sensor output (20–200 mV full scale) in HVAC control units. IC Role / Device Role / Timing Role: Quad amplifier configures two channels as differential input stages, one as reference buffer, one as low-pass filter driver. Use Value: 0.8 mV offset ensures <0.4% measurement error at 200 mV FS; 125 °C rating avoids thermal drift compensation circuitry. |
Use Scenario: Biopotential signal amplification in battery-powered wearable ECG devices with 3-lead configuration. IC Role / Device Role / Timing Role: Three channels implement lead-I, lead-II, and Wilson central terminal amplifiers; fourth channel buffers reference voltage. Use Value: 180 µA/channel current enables >100-hour battery life on CR2032; rail-to-rail output matches 1.8 V ADC input range. |
| Industrial Thermocouple Signal Conditioning | Smart Battery Fuel Gauge Interface |
|
Use Scenario: Cold-junction compensation and linearization of K-type thermocouple outputs in programmable logic controllers. IC Role / Device Role / Timing Role: One channel amplifies thermocouple voltage, two configure precision instrumentation amp topology, one drives ADC reference. Use Value: 1 µV/°C offset drift minimizes calibration frequency; 2.3 V min supply allows direct use with buck-converted 2.5 V rails. |
Use Scenario: Amplifying voltage and current sense signals from smart battery packs (e.g., 4S LiPo) in portable power tools. IC Role / Device Role / Timing Role: Two channels condition cell voltage sense lines, one amplifies shunt current sense, one filters coulomb counter reference. Use Value: Shutdown pins allow independent disabling of unused sensing paths during standby, cutting leakage to <1 µA total. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV854AIDT | Enhanced input offset voltage (0.8 mV max vs. 4 mV max for non-A version); identical SO14 pinout and shutdown behavior. | Preferred for <0.1% accuracy-critical sensor front-ends where offset calibration is impractical. | Select TSV854AIDT when offset drift and initial Vio dominate system error budget over cost sensitivity. |
| LMV324QDRQ1 | Higher supply current (250 µA/ch), lower GBP (1 MHz), no shutdown feature; AEC-Q100 qualified but wider Vio distribution (±3 mV). | Suitable for cost-sensitive automotive body electronics where shutdown is unnecessary and 125 °C operation is still required. | Choose LMV324QDRQ1 only if existing design uses LMV324 footprint and shutdown is not needed - no pin compatibility with TSV854IYPT's dual SHDN pins. |
Compared with TSV854IYPT, TSV854AIDT improves DC accuracy without changing layout or firmware, while LMV324QDRQ1 trades power efficiency and precision for lower unit cost and simpler control interface - making it viable only in non-shutdown, non-battery-critical roles.

FAQ
What is the maximum capacitive load the TSV854IYPT can drive while maintaining stability?
The TSV854IYPT maintains ≥60° phase margin with up to 200 pF capacitive load when configured as a unity-gain buffer, as confirmed in Figure 11 of DocID022468 Rev 4. For loads exceeding 200 pF, a series isolation resistor (≥100 Ω) between output and capacitance is required to prevent peaking or oscillation.
Can the SHDN1/2 and SHDN3/4 pins be tied together to control all four amplifiers with one signal?
Yes - connecting SHDN1/2 and SHDN3/4 to a common logic line enables simultaneous shutdown of all four amplifiers. This configuration draws ≤200 nA total supply current at 25 °C and places all outputs in high-impedance state, as verified in Table 5 and Section 4.7.
Does the TSV854IYPT support true rail-to-rail input common-mode range?
No - the input common-mode range extends from VCC− − 0.2 V to VCC+ − 1 V, meaning it includes ground but does not reach the positive rail. This allows accurate amplification of signals near 0 V in single-supply systems, but inputs above VCC+ − 1 V risk phase reversal or increased distortion.
Is the SO14 package of TSV854IYPT RoHS and REACH compliant?
Yes - TSV854IYPT carries STMicroelectronics' ECOPACK®2 certification, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation is accessible via ST's quality portal using device-specific lot traceability.
