Product details
Overview
TSV854AIYPT 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, 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 TSV854AIYPT datasheet, TSV854AIYPT pinout, TSV854AIYPT application, or TSV854AIYPT equivalent, key selection criteria include its automotive-grade qualification, low-power shutdown mode (50 nA), extended temperature performance, and compatibility with compact SC70-5/SO14/TSSOP14 packages for space-constrained designs.
Technical Context
The TSV854AIYPT integrates four independent op-amps with individual shutdown control (SHDN1–SHDN4), enabling selective channel power gating. Its input stage supports rail-to-rail common-mode range (VCC− − 0.2 V to VCC+ − 1 V) and features low input bias current (27–60 nA typ) and high CMRR (72–75 dB).
Each amplifier provides rail-to-rail output swing (≤180 mV from rails into 10 kΩ), 0.7 V/µs slew rate at 5 V, and stable operation with capacitive loads up to 1 nF-validated by phase margin ≥60° and gain margin ≥10 dB under typical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffering and low-frequency active filtering up to ~1 MHz. |
| Input Offset Voltage | 0.8 mV max at 25 °C - enables accurate DC-coupled amplification without calibration in sensor front-ends. |
| Supply Current per Channel | 180 µA max at 5 V - allows four-channel operation while drawing <720 µA total, ideal for ultra-low-power battery systems. |
| Shutdown Current | 50 nA max per channel - reduces system standby power by >99.9% versus active mode, critical for always-on automotive modules. |
| Operating Temperature Range | –40 °C to +125 °C - fully specified for under-hood automotive applications and industrial environments. |
| Rail-to-Rail Output | Swings within 100 mV of rails into 2 kΩ - maximizes dynamic range in single-supply 3.3 V or 5 V systems. |
| Common-Mode Input Range | VCC− − 0.2 V to VCC+ − 1 V - accepts ground-referenced inputs and supports high-side current sensing. |
Pinout & Package
The TSV854AIYPT is packaged in a 14-lead TSSOP (Thin Shrink Small Outline Package) with exposed pad, optimized for thermal performance and PCB area efficiency in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | In+ (non-inverting input) | Positive differential input for each of four op-amp channels; accepts signals down to VCC− − 0.2 V. |
| 2, 4, 6, 11 | In− (inverting input) | Negative differential input; matched to In+ for precision closed-loop configurations. |
| 7, 8, 10, 13 | Out (output) | Rail-to-rail output capable of sourcing/sinking ≥35 mA (typ) at 5 V; high-Z in shutdown. |
| 9 | VCC+ | Positive supply rail (2.3–5.5 V); decoupling capacitor required per layout guidelines. |
| 14 | VCC− | Negative supply rail (typically GND); reference for all inputs, outputs, and shutdown logic. |
| 15, 16, 17, 18 | SHDN1–SHDN4 | Active-high digital enable pins; pulling low disables corresponding amplifier and reduces ICC to ≤50 nA. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 qualified - validated for reliability in automotive signal chains including engine control and ADAS sensors. |
| Low input offset drift | 1 µV/°C max over –40 °C to +125 °C - maintains accuracy across thermal cycling without recalibration. |
| High ESD tolerance | 4 kV HBM (3.5 kV on SHDN pins) - withstands handling and board-level transients in manufacturing and field use. |
| Stable with capacitive loads | Phase margin ≥60° with CL ≤ 1 nF - eliminates need for isolation resistors in driving ADC inputs or cables. |
| Shutdown propagation delay | 300 ns turn-on / 20 ns turn-off - enables fast power cycling in time-triggered control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV854IYPT | No shutdown feature; identical offset, bandwidth, and supply specs but lacks SHDN pins. | Suitable only where full-time operation is required; no channel-level power control. | Select when system-level power sequencing eliminates need for per-amplifier shutdown. |
| LMV854QDGKR | Higher GBP (5.5 MHz), higher supply current (1.2 mA/ch), wider offset range (3.5 mV max), not AEC-Q100 qualified. | Targeted at non-automotive portable instrumentation requiring faster settling. | Choose for bandwidth-critical designs where automotive qualification is unnecessary and higher power is acceptable. |
Compared with TSV854IYPT, the TSV854AIYPT adds per-channel shutdown with negligible impact on offset or bandwidth, while LMV854QDGKR trades automotive robustness and ultra-low power for speed-making TSV854AIYPT optimal for thermally demanding, safety-conscious, and energy-constrained automotive subsystems.

FAQ
What is the maximum capacitive load the TSV854AIYPT can drive while maintaining stability?
The TSV854AIYPT maintains ≥60° phase margin with capacitive loads up to 1 nF when configured as a unity-gain buffer, as verified in Figure 11 of the datasheet. For loads >200 pF, a series resistor (≥10 Ω) between output and load is recommended to ensure robust stability across temperature and process variation.
Can the SHDN pins be tied together and controlled by a single microcontroller GPIO?
Yes-SHDN1 through SHDN4 are independently controllable but electrically compatible; tying them together to one GPIO is valid. Each pin draws only 10 pA leakage current when high, so a standard MCU output can drive all four simultaneously without loading concerns or timing skew.
Does the TSV854AIYPT support true rail-to-rail input operation?
No-the input common-mode range extends from VCC− − 0.2 V to VCC+ − 1 V, meaning it includes the negative rail but stops 1 V below the positive rail. This allows ground-referenced inputs but excludes direct VCC+ sampling; external level-shifting is needed for full rail-to-rail input capability.
How does the device behave during power-up if SHDN pins are left unconnected?
Leaving SHDN pins floating is strictly prohibited per Section 4.7 of the datasheet. The pins must be actively pulled to VCC+ (to enable) or VCC− (to disable). Uncontrolled states may cause undefined output behavior, increased current draw, or latch-up risk; a 100 kΩ pull-up to VCC+ is recommended for default-enable operation.
