Product details
Overview
TSV992AIYST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in MiniSO8 package, optimized for low-voltage (2.5–5.5 V), low-power (820 µA typ.) applications requiring 20 MHz gain-bandwidth, ±3 V/V minimum stable gain, and ultra-low input bias current (1 pA typ.). It serves as a precision signal-conditioning front-end in battery-powered medical sensors and automotive body electronics.
For engineers reviewing the TSV992AIYST datasheet, TSV992AIYST pinout, TSV992AIYST application, or TSV992AIYST equivalent, key selection criteria include its A-grade 1.5 mV max input offset voltage, 35 mA output drive capability, -40 °C to 125 °C automotive temperature range, and stability requirements for gains ≥4 or ≤-3 - critical for active filtering and sensor interface designs.
Technical Context
The TSV992AIYST implements a high-speed, low-noise CMOS input stage enabling rail-to-rail operation with 21 nV/√Hz input voltage noise at 10 kHz and 10 V/μs slew rate. Its internal compensation requires minimum closed-loop gain of 4 (non-inverting) or -3 (inverting) for phase margin ≥45° with 100 pF capacitive load.
It features ultra-low input bias current (1 pA typ.) and common-mode input range extending 0.1 V beyond rails, supporting direct interfacing with high-impedance sources like piezoelectric sensors or pH electrodes. Supply rejection (70–86 dB) and CMRR (55–82 dB) are specified across full temperature range (-40 °C to 125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct integration into single-cell Li-ion (3.0–3.7 V) and 3.3 V logic systems without level-shifting. |
| Gain-Bandwidth Product | 20 MHz - supports high-fidelity amplification of signals up to ~5 MHz in gain-of-4 configuration. |
| Input Offset Voltage (A grade) | 1.5 mV max at 25 °C - ensures <0.3% error in 0.5 V full-scale sensor outputs without trimming. |
| Quiescent Current | 820 µA per channel typ. - allows dual-channel operation on microampere-budget battery systems for >1-year runtime. |
| Output Drive | ±35 mA - drives 600 Ω loads to rail with <150 mV saturation, suitable for driving ADC reference buffers or LED bias circuits. |
| Input Bias Current | 1 pA typ. - minimizes voltage error across >1 GΩ source impedances, critical for photodiode and electrochemical sensor interfaces. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 for under-hood automotive use and industrial edge nodes. |
Pinout & Package
TSV992AIYST uses the MiniSO8 (8-pin) package (3.0 mm × 3.0 mm, 0.65 mm pitch), with exposed pad unconnected per datasheet. Pin 1 = IN1−, Pin 2 = IN1+, Pin 3 = OUT1, Pin 4 = VCC−, Pin 5 = VCC+, Pin 6 = IN2−, Pin 7 = IN2+, Pin 8 = OUT2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts differential signal referenced to non-inverting input; supports rail-to-rail common-mode range. |
| 2 | Non-inverting input (Channel 1) | High-impedance node (1 pA bias); connects directly to high-Z sensors without loading error. |
| 3 | Output (Channel 1) | Rail-to-rail swing capable of sourcing/sinking 35 mA; requires decoupling capacitor near VCC pins. |
| 4 | Negative supply (VCC−) | Ground reference for dual-supply operation or system ground in single-supply configurations. |
| 5 | Positive supply (VCC+) | Accepts 2.5–5.5 V; must be decoupled with 10 nF ceramic capacitor placed within 2 mm. |
| 6 | Inverting input (Channel 2) | Independent second channel input; identical electrical specs to Channel 1. |
| 7 | Non-inverting input (Channel 2) | Enables dual-sensor conditioning (e.g., differential thermocouple + RTD) on single IC. |
| 8 | Output (Channel 2) | Full rail-to-rail output drive; supports independent feedback networks per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.1 V beyond rails; output swings within 15 mV of rails at 10 kΩ load - enables full dynamic range utilization in 3.3 V systems. |
| Stability architecture | Internally compensated for minimum gain of 4 (non-inverting) or -3 (inverting) - eliminates need for external compensation in most gain-setting configurations. |
| Ultra-low input bias current | 1 pA typical - reduces offset drift in high-impedance transducer interfaces (e.g., glass pH electrode, piezo element) by >100× vs. bipolar op-amps. |
| Automotive qualification | AEC-Q100 Grade 1 compliant (-40 °C to +125 °C) with advanced screening - validated for engine control modules and ADAS sensor fusion units. |
| Low-noise performance | 21 nV/√Hz at 10 kHz - preserves SNR in precision instrumentation chains where 16-bit ADC resolution must be maintained. |

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 | Standard grade (7.5 mV max Vio), SO8 package, commercial temp range (-40 °C to 85 °C) | Lacks AEC-Q100 qualification; unsuitable for under-hood automotive use | Select when cost sensitivity outweighs automotive reliability requirements and offset tolerance >1.5 mV is acceptable. |
| TSV912AIST | 8 MHz GBP, same A-grade offset (1.5 mV), identical MiniSO8 footprint and pinout | Lower bandwidth limits use in >2 MHz active filters or fast-settling data acquisition | Choose for ultra-low-power (<600 µA) applications where 20 MHz bandwidth is unnecessary and thermal dissipation must be minimized. |
Compared with TSV992IDT, TSV992AIYST provides tighter offset and extended temperature range for automotive deployment; versus TSV912AIST, it delivers 2.5× higher bandwidth at only +220 µA supply current - making it optimal for high-fidelity sensor signal chains demanding both precision and speed.

FAQ
What is the minimum stable gain configuration for TSV992AIYST?
The TSV992AIYST requires a minimum closed-loop gain of 4 in non-inverting configurations or -3 in inverting configurations to maintain ≥45° phase margin with 100 pF capacitive load. Using it in unity-gain follower mode requires an external series resistor (≥100 Ω) at the output to ensure stability, as confirmed in Section 5.1 of DS4975 Rev 16.
Is the exposed pad on the MiniSO8 package electrically connected?
No - the exposed pad on the TSV992AIYST MiniSO8 package is not internally connected to any die node. Per Figure 20 and note on DS4975 page 17, it may be soldered to PCB ground plane for thermal enhancement or left floating; no electrical function is assigned to it.
How does the 1.5 mV max input offset voltage impact DC-coupled sensor designs?
At 1.5 mV max (A grade), the TSV992AIYST introduces ≤0.03% error in a 5 V full-scale system, enabling direct DC-coupled amplification of millivolt-level transducer outputs (e.g., load cells, thermopiles) without nulling circuitry - reducing BOM count and board area in portable instrumentation.
Can TSV992AIYST drive a 1000 pF capacitive load directly?
No - the TSV992AIYST is not unity-gain stable and exhibits peaking with >100 pF capacitive loads in standard configurations. For 1000 pF loads, stability requires either a series isolation resistor (≥470 Ω) at the output or a feedback capacitor (e.g., 2.2 pF) across the gain-setting resistor, as demonstrated in Figures 16 and 17 of DS4975 Rev 16.
