Product details
Overview
TSV992IYST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 20 MHz gain-bandwidth at ≥4 or ≤−3 minimum stable gain, 1.5 mV max input offset voltage (A grade), 820 µA typical supply current per channel, and 35 mA output drive capability across 2.5 V to 5.5 V operation - enabling precision signal conditioning in battery-powered medical sensors and automotive body control modules.
For engineers reviewing the TSV992IYST datasheet, TSV992IYST pinout, TSV992IYST application, or TSV992IYST equivalent, key selection criteria include its A-grade offset voltage spec, non-unity-gain stability requirement (gain ≥4 or ≤−3), rail-to-rail I/O swing at 2.5 V supply, and MiniSO8 package compatibility with space-constrained portable designs.
Technical Context
The TSV992IYST employs a high-speed, low-power CMOS input stage delivering 1 pA typical input bias current and 21 nV/√Hz input voltage noise at 10 kHz. Its internal compensation ensures phase margin ≥45° only when configured for gain ≥4 (non-inverting) or ≤−3 (inverting), requiring external stabilization (e.g., series output resistor or feedback capacitor) for unity-gain follower use.
It operates over −40 °C to +125 °C with common-mode input range extending 0.1 V beyond rails and output swing within 15 mV of rails (RL = 10 kΩ). Supply rejection ratio reaches 86 dB and CMRR is 82 dB at 5 V supply, supporting accurate DC-coupled sensor interfacing in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 20 MHz - enables closed-loop bandwidth up to ~5 MHz at gain = 4, suitable for active anti-aliasing filters in data acquisition. |
| Input offset voltage (max) | 1.5 mV - limits DC error to <0.75% of full-scale in 2 V-output sensor amplifiers without trimming. |
| Supply current per channel | 820 µA typ. - supports >100-hour runtime on coin-cell batteries in portable ECG front-ends. |
| Output drive current | ±35 mA - drives 600 Ω loads directly, eliminating need for external buffer stages in analog output circuits. |
| Input bias current | 1 pA typ. - prevents significant voltage drop across >100 MΩ source impedances (e.g., piezoelectric or pH sensors). |
| Common-mode input range | (VCC−) −0.1 V to (VCC+) +0.1 V - accepts signals down to ground or up to supply rail, simplifying single-supply transducer interfacing. |
| Slew rate | 10 V/µs - supports 10 kHz full-power sine waves at 20 Vpp without distortion, adequate for audio and ultrasonic signal paths. |
Pinout & Package
TSV992IYST is supplied in MiniSO8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), featuring exposed pad not internally connected - may be grounded or left floating per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback network connection; requires matched trace impedance for optimal CMRR at high frequencies. |
| 2 | Non-inverting input (Channel 1) | High-impedance node; sensitive to PCB leakage - guard ring recommended for pA-level bias current preservation. |
| 3 | VCC− (GND) | Power return path; must connect to low-impedance ground plane adjacent to decoupling capacitors. |
| 4 | Output (Channel 1) | Capable of sourcing/sinking ±35 mA; requires series resistor (≥10 Ω) if driving >100 pF capacitive load in unity-gain configuration. |
| 5 | Output (Channel 2) | Independent output stage; shares VCC−/VCC+ rails - cross-talk <−80 dB at 10 kHz under typical loading. |
| 6 | Non-inverting input (Channel 2) | Electrically isolated from Channel 1 inputs; same bias current and offset specs apply. |
| 7 | Inverting input (Channel 2) | Configurable for differential or single-ended feedback; pin 7–6 differential pair supports instrumentation amp topologies. |
| 8 | VCC+ | Positive supply rail; requires 10 nF ceramic decoupling capacitor placed ≤2 mm from pin per ST recommendation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization from 2.5 V supply - no level-shifting needed for 0–2.5 V sensor outputs. |
| Low input offset voltage (A grade) | 1.5 mV max ensures <0.06% gain error in 2.5 V reference-based current-sense amplifiers. |
| Stable for gain ≥4 or ≤−3 | Eliminates need for external compensation in standard gain-of-5 or inverting gain-of-4 configurations used in industrial I/V conversion. |
| Ultra-low input bias current | 1 pA typ. preserves accuracy in high-impedance photodiode transimpedance amplifiers without guard traces. |
| Wide operating temperature range | −40 °C to +125 °C supports under-hood automotive placement and industrial motor-control feedback loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV992IDT | SO8 package (5.0 mm × 4.0 mm), higher thermal resistance (125 °C/W vs. MiniSO8's 190 °C/W), same electrical specs. | Preferred for prototyping or legacy board layouts with SO8 footprints; less suitable for ultra-compact portable devices. | Select when board space allows larger footprint and thermal management uses heatsinking or airflow. |
| TSV912IST | 8 MHz GBP, unity-gain stable, 550 µA supply current, 1.8 mV max offset (standard grade), same MiniSO8 package. | Better for low-frequency, ultra-low-power applications (e.g., environmental sensors) where 20 MHz bandwidth is unnecessary. | Choose when power budget is tighter (<500 µA/channel) and signal bandwidth <100 kHz suffices. |
Compared with TSV992IDT, TSV992IYST offers identical performance in a 30% smaller footprint but with higher thermal resistance; versus TSV912IST, it trades 2.5× higher bandwidth and 1.5× higher output drive for +270 µA supply current and tighter offset spec.

FAQ
Is TSV992IYST unity-gain stable?
No, TSV992IYST is not unity-gain stable. It requires minimum closed-loop gain of 4 (non-inverting) or −3 (inverting) for phase margin ≥45°. For unity-gain follower use, ST recommends adding a 10–47 Ω series resistor at the output and verifying stability via bench testing and simulation with the official macromodel.
What is the maximum capacitive load the TSV992IYST can drive?
TSV992IYST can reliably drive up to 100 pF capacitive load when configured for gain ≥4 with proper PCB layout (short traces, ground plane, 10 nF decoupling). Driving >100 pF requires external compensation - either an output series resistor (per Figure 16) or feedback capacitor (per Figure 17) - validated through SPICE simulation and lab measurement.
Does the exposed pad on the MiniSO8 package require connection?
No, the exposed pad on the TSV992IYST MiniSO8 package is not internally connected. ST specifies it may be left floating or connected to VCC− (ground) for improved thermal dissipation or mechanical anchoring - no electrical function is assigned to it in the die design.
How does the A-grade offset specification impact system calibration?
The 1.5 mV max input offset voltage (A grade) reduces or eliminates the need for factory calibration in systems with ≤12-bit effective resolution. For example, in a 2.5 V full-scale 12-bit ADC system, this offset contributes <2.5 LSB error - acceptable for many industrial sensor interfaces without software or hardware trimming.
