Product details
Overview
TSV852IYDT from STMicroelectronics is a dual-channel, rail-to-rail output operational amplifier with shutdown functionality, designed for precision signal conditioning in low-voltage, power-constrained 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 - enabling use in automotive sensor front-ends and portable medical monitors.
For engineers reviewing the TSV852IYDT datasheet, TSV852IYDT pinout, TSV852IYDT application, or TSV852IYDT equivalent, key selection criteria include its dual-channel shutdown control, rail-to-rail output swing (≤180 mV from rails), low 50 nA shutdown current, extended temperature qualification, and compatibility with 2.3 V–5.5 V single-supply operation.
Technical Context
The TSV852IYDT integrates two independent amplifiers with individual shutdown pins (SHDN1, SHDN2), enabling selective channel disablement without affecting the other. Its input stage supports common-mode voltages down to VCC− − 0.2 V and up to VCC+ − 1 V, with no phase reversal - critical for ground-referenced sensor interfaces.
Each amplifier features unity-gain-stable compensation, 0.6–0.7 V/µs slew rate, 70–75 dB CMRR at 25 °C, and 72–79 dB PSRR, ensuring stable closed-loop performance in noisy automotive and industrial environments with capacitive loads up to 200 pF.
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 domains without level shifting. |
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffer and 10× gain configurations up to ~130 kHz with adequate phase margin. |
| Input Offset Voltage | 0.8 mV max at 25 °C - reduces DC error in precision transducer amplification (e.g., strain gauge, thermopile) without trimming. |
| Supply Current per Channel | 180 µA max at 5 V - extends battery life in always-on wearable sensors and remote IoT nodes. |
| Shutdown Current | 50 nA max per channel - allows microamp-level system sleep modes while retaining fast wake-up (<300 ns turn-on). |
| Rail-to-Rail Output Swing | ≤180 mV from VCC+ or VCC− with 10 kΩ load - maximizes dynamic range in single-supply data acquisition systems. |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood automotive signal conditioning. |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm × 1.2 mm), lead pitch 0.65 mm, exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1+ | Non-inverting input of Channel 1 - accepts signals down to VCC− − 0.2 V, suitable for ground-referenced sensors. |
| 2 | In1− | Inverting input of Channel 1 - used for feedback configuration; high impedance (>10¹² Ω) minimizes loading on high-Z sources. |
| 3 | Out1 | Output of Channel 1 - rail-to-rail swing enables full utilization of ADC input range in 3.3 V systems. |
| 4 | VCC− | Negative supply rail - shared reference for both amplifiers and shutdown logic; must be connected to system ground or negative rail. |
| 5 | In2+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1; supports dual-sensor differential measurement. |
| 6 | In2− | Inverting input of Channel 2 - configured independently; supports active filtering or instrumentation amp topologies. |
| 7 | Out2 | Output of Channel 2 - high-impedance state during shutdown (SHDN2 = low), preventing back-driving of downstream circuitry. |
| 8 | VCC+ | Positive supply rail - powers both amplifiers and internal bias networks; requires local 10 nF decoupling. |
| 9 | SHDN1 | Shutdown control for Channel 1 - logic high (≥VCC− + 0.5 V) enables amplifier; logic low disables with 50 nA quiescent draw. |
| 10 | SHDN2 | Shutdown control for Channel 2 - independent of SHDN1; allows asymmetric power management in multi-channel systems. |
| 11–14 | No Connect / Exposed Pad | Thermal pad (pin 14) - recommended to connect to PCB ground plane for improved thermal dissipation and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive-grade qualification | Qualified per AEC-Q100 Grade 1 (-40 °C to +125 °C), enabling deployment in engine control, cabin sensing, and ADAS subsystems. |
| Individual channel shutdown | Dual independent SHDN pins allow granular power control - e.g., disable one channel during idle while keeping the other active for wake-on-event detection. |
| Rail-to-rail output with low saturation voltage | Output swings within 180 mV of rails into 10 kΩ, preserving >94% of full-scale range in 3.3 V ADC systems without external level-shifting. |
| High ESD tolerance | 4 kV HBM (non-shutdown pins), 3.5 kV HBM (SHDN pins), and 1.3 kV CDM - reduces field failure risk in handling and assembly of automotive modules. |
| Low input offset drift | 1 µV/°C max over -40 °C to +125 °C - ensures <120 µV total offset shift across full temperature range, critical for uncalibrated medical sensors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, shutdown-enabled op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV852IST | Same die, SO-8 package (no shutdown pins); 180 µA supply current, same GBW and Vio. | Lacks channel-level shutdown; suited for space-constrained non-automotive designs where power gating is handled externally. | Select when board layout prohibits TSSOP-14 or when shutdown functionality is unnecessary. |
| LMV822QDRQ1 | 5.5 MHz GBW, higher 1.3 mA supply current per channel, no shutdown, AEC-Q100 qualified. | Better bandwidth but 7× higher quiescent current; not suitable for battery-critical applications. | Select only when >1 MHz closed-loop bandwidth is required and system power budget permits. |
Compared with TSV852IYDT, TSV852IST sacrifices shutdown control for smaller footprint and lower cost, while LMV822QDRQ1 trades ultra-low power for higher speed - making TSV852IYDT optimal for automotive and portable systems demanding both precision and nanowatt-level sleep states.

FAQ
What is the maximum capacitive load the TSV852IYDT can drive stably?
The TSV852IYDT maintains ≥60° phase margin with up to 200 pF capacitive load when driving a 50 kΩ resistive load, as verified in Figure 9 of the datasheet. For loads exceeding 200 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is required to prevent peaking or oscillation - especially critical in PCB traces feeding ADC inputs or long cables.
Can the SHDN pins be left unconnected?
No - the SHDN1 and SHDN2 pins must never be left floating. Per Section 4.7, each shutdown pin must be actively tied to either VCC+ (to enable) or VCC− (to disable). Floating pins may cause undefined output states, increased current consumption, or latch-up risk due to internal MOSFET gate instability.
Does the TSV852IYDT support single-supply operation with input signals below ground?
No - the input common-mode range extends to VCC− − 0.2 V, but does not support true negative inputs below the negative rail. With VCC− = 0 V (ground), the minimum valid input is −0.2 V. For bipolar signal handling, a split supply (e.g., ±2.5 V) or level-shifting circuit is required.
How does the output behave during shutdown?
When SHDN1 or SHDN2 is pulled low, the corresponding amplifier output enters a high-impedance (Hi-Z) state - neither sourcing nor sinking current. The output voltage floats and must be externally biased or clamped if connected to downstream circuitry, as confirmed in Table 5 and Figure 23–24 of the datasheet.
