Product details
Overview
TSV992AIYDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for automotive-grade applications, featuring 20 MHz gain-bandwidth, 1.5 mV max input offset voltage (A grade), 820 µA typical supply current per channel, ±35 mA output drive, and operation from 2.5 V to 5.5 V. It is used in precision sensor signal conditioning within AEC-Q100-compliant vehicle subsystems.
For engineers reviewing the TSV992AIYDT datasheet, TSV992AIYDT pinout, TSV992AIYDT application, or TSV992AIYDT equivalent, key selection considerations include its minimum stable gain requirement (≥4 or ≤−3), ultra-low 1 pA typical input bias current, −40 °C to +125 °C automotive temperature range, and SO8 package with exposed pad not internally connected.
Technical Context
The TSV992AIYDT employs a high-speed, low-power CMOS input stage enabling rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V) and rail-to-rail output swing. Its 20 MHz gain-bandwidth product is specified at 2 kΩ load and 100 pF capacitive load, with phase margin ≥45° only when configured for gain ≥4 (non-inverting) or ≤−3 (inverting).
It delivers 35 mA sourcing/sinking capability while maintaining low distortion (0.0014% THD+N at 5 V supply, 1 kHz, 4.4 Vpp), 21 nV/√Hz input voltage noise, and 82 dB supply voltage rejection ratio - making it suitable for battery-constrained, noise-sensitive analog front-ends where stability under capacitive loads must be managed via external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 20 MHz - supports closed-loop bandwidth up to ~5 MHz at gain = 4, enabling fast signal conditioning in sensor interfaces. |
| Input offset voltage (max) | 1.5 mV - ensures <0.3% error in 0–5 V measurement ranges without trimming, critical for automotive sensor accuracy. |
| Supply current per channel | 820 µA typ. - enables dual-opamp operation below 1.7 mA total, suitable for always-on vehicle modules with strict power budgets. |
| Output current (sourcing/sinking) | ±35 mA - drives 150 Ω loads directly (e.g., 5 V DAC buffers or ADC reference drivers) without external boost stages. |
| Common-mode input range | VCC− − 0.1 V to VCC+ + 0.1 V - accepts signals across full supply rail, simplifying single-supply interfacing with transducers and resistive sensors. |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1, validated for under-hood and cabin control unit deployment. |
| Input bias current | 1 pA typ. - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without guard traces. |
Pinout & Package
TSV992AIYDT is supplied in an SO8 package (8-pin small outline integrated circuit) with standard pinout and no internal connection to the exposed thermal pad. Pin 1 is marked by a notch or dot; the pad may be grounded or left floating per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback signal in inverting configurations; high-impedance node requiring guarded routing. |
| 2 | Non-inverting input (Channel 1) | Reference input for Channel 1; rail-to-rail common-mode range enables direct connection to sensor outputs. |
| 3 | Output (Channel 1) | Delivers rail-to-rail swing; capable of ±35 mA drive into resistive or moderate capacitive loads. |
| 4 | VCC− (Ground) | Power return for both channels; requires local 10 nF decoupling to minimize PSRR degradation. |
| 5 | Output (Channel 2) | Independent output for second channel; shares same supply rails and thermal characteristics as Channel 1. |
| 6 | Non-inverting input (Channel 2) | Reference input for Channel 2; electrically isolated from Channel 1 inputs except through shared supply rails. |
| 7 | Inverting input (Channel 2) | Feedback node for Channel 2; matched offset and bias performance to Channel 1 enables differential pair use. |
| 8 | VCC+ | Positive supply rail (2.5–5.5 V); connects to bulk capacitor and local 10 nF decoupling near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply systems (e.g., 3.3 V microcontroller ADC references). |
| AEC-Q100 qualified | Validated for automotive Grade 1 (−40 °C to +125 °C), including HTOL, TC, and ESD testing per Q100 Rev H. |
| Stable at gain ≥4 or ≤−3 | Eliminates need for unity-gain stable op-amps in higher-gain signal chains, reducing power vs. alternatives like TSV912. |
| Ultra-low input bias current | 1 pA typ. preserves signal integrity in high-Z sensor circuits (e.g., thermopile amplifiers) without active guarding. |
| Low THD+N | 0.0014% at 1 kHz allows clean amplification of audio or ultrasonic sensor signals without harmonic contamination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912AIDT | 8 MHz GBP, unity-gain stable, 1.1 mA ICC, same SO8 package and AEC-Q100 qualification. | Lower bandwidth limits use in >2 MHz filter or fast-settling applications; better for DC-coupled sensor buffers. | Select when unity-gain stability is mandatory and 20 MHz bandwidth is unnecessary - reduces design complexity. |
| LMV722QDRQ1 | 10 MHz GBP, 1.25 mA ICC, rail-to-rail I/O, AEC-Q100 Grade 1, but 3.5 mV max Vio and 10 pA Iib. | Higher offset and bias current degrade accuracy in high-impedance or precision DC applications. | Choose only if legacy TI ecosystem compatibility outweighs TSV992AIYDT's 2.3× lower input bias current and 2.3× lower offset. |
Compared with TSV912AIDT, TSV992AIYDT trades unity-gain stability for 2.5× higher bandwidth and 25% lower quiescent current; versus LMV722QDRQ1, it delivers superior DC precision and noise performance at identical automotive qualification level.

FAQ
Is TSV992AIYDT unity-gain stable?
No. The TSV992AIYDT is not unity-gain stable and requires a minimum closed-loop gain of 4 (non-inverting) or −3 (inverting) to maintain ≥45° phase margin. Using it as a voltage follower without external compensation (e.g., series output resistor or feedback capacitor) risks oscillation, especially with capacitive loads exceeding 100 pF.
What is the function of the exposed pad on the SO8 package?
The exposed pad on the TSV992AIYDT SO8 package is not internally connected to any die node. It may be soldered to a ground plane for improved thermal dissipation or left floating - neither choice affects electrical performance. ST recommends connecting it to VCC− for optimal thermal resistance (125 °C/W).
Can TSV992AIYDT drive a 600 Ω load?
Yes. At 5 V supply, TSV992AIYDT delivers ±35 mA output current, enabling direct driving of 600 Ω loads with ≤150 mV saturation voltage (VOL/VOH). Output swing remains rail-to-rail under this load, supporting interface with legacy 5 V logic or analog standards without level-shifting.
How does the A grade (TSV992A) differ from standard TSV992?
The "A" suffix denotes tighter input offset voltage specification: 1.5 mV max (vs. 4.5 mV max for standard grade) at 25 °C, and 3 mV max over full temperature range (−40 °C to +125 °C). This improves absolute accuracy in precision measurement applications without requiring system-level trimming.
