Product details
Overview
TSV992AIDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in SO8 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 conditioner in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TSV992AIDT datasheet, TSV992AIDT pinout, TSV992AIDT application, or TSV992AIDT equivalent, key selection criteria include its A-grade 1.5 mV max input offset voltage, 35 mA output drive capability, rail-to-rail swing at 5 V supply, stability constraints (gain ≥ 4 or ≤ –3), and SO8 thermal resistance (125 °C/W).
Technical Context
The TSV992AIDT implements a high-speed, low-noise CMOS input stage enabling 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 with closed-loop gain ≥ 4 (non-inverting) or ≤ –3 (inverting), excluding unity-gain follower use without external stabilization.
It operates across –40 °C to +125 °C with common-mode input range extending 0.1 V beyond rails and supports capacitive loads up to 100 pF when paired with appropriate feedback network design - including optional series output resistor or parallel feedback capacitor per ST application note DS4975 Section 5.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 20 MHz - enables accurate amplification of signals up to ~5 MHz at gain = 4 without significant roll-off |
| Input offset voltage (max) | 1.5 mV - limits DC error in precision sensor front-ends and active filter DC bias points |
| Supply current per channel | 820 µA typ. - supports >10-year operation on coin-cell batteries in always-on portable devices |
| Output current drive | ±35 mA - drives 600 Ω loads directly without external buffer stages |
| Input bias current | 1 pA typ. - minimizes leakage-induced errors in high-impedance pH, photodiode, or piezoelectric sensor interfaces |
| Common-mode input range | (VCC−) − 0.1 V to (VCC+) + 0.1 V - accepts inputs at ground or rail in single-supply systems |
| Slew rate | 10 V/µs - supports clean 1 Vpp signal reproduction up to ~1.6 MHz before slew limiting |
Pinout & Package
TSV992AIDT is supplied in an 8-pin SO8 (Small Outline Integrated Circuit) package with exposed pad not internally connected. Pin 1 is marked by notch or dot; device orientation follows JEDEC MS-012 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback signal in inverting configurations; referenced to VCC− for common-mode range |
| 2 | Non-inverting input (Channel 1) | Reference node for differential sensing; supports rail-to-rail common-mode voltage |
| 3 | Output (Channel 1) | Delivers rail-to-rail swing; capable of sourcing/sinking 35 mA into resistive loads |
| 4 | VCC− (Ground) | Power return path; decoupling capacitor must be placed within 2 mm per layout guidelines |
| 5 | Inverting input (Channel 2) | Independent input for second op-amp channel; electrically isolated from Channel 1 |
| 6 | Non-inverting input (Channel 2) | Enables dual-channel signal conditioning without cross-talk in shared supply domains |
| 7 | Output (Channel 2) | Provides identical AC/DC performance to Pin 3; shares same VCC+ and VCC− rails |
| 8 | VCC+ | Positive supply rail (2.5–5.5 V); requires 10 nF ceramic decoupling capacitor adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V or 5 V single-supply systems without level-shifting circuitry |
| Low input offset voltage (A grade) | 1.5 mV max ensures <0.03% gain error in 50 mV biomedical sensor outputs amplified 20× |
| Stable at gain ≥ 4 or ≤ –3 | Eliminates need for external compensation in fixed-gain instrumentation amplifier stages |
| Ultra-low input bias current | 1 pA typ. prevents >100 kΩ source impedance from inducing >100 µV offset in transimpedance configurations |
| High ESD immunity | 5 kV HBM rating allows direct handling in non-ESD-controlled assembly environments |

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 vs. 1.5 mV), otherwise identical electrical specs and SO8 footprint | Acceptable where sensor output amplitude >100 mV or system calibrates out offset | Select when cost sensitivity outweighs need for A-grade precision |
| TSV912AIST | Lower GBP (8 MHz), lower supply current (600 µA), same 1.5 mV Vio and rail-to-rail I/O | Better suited for sub-2 MHz signal chains where power budget is tighter than bandwidth requirement | Choose for ultra-low-power portable devices with bandwidth ≤ 1 MHz |
Compared with TSV992IDT, the TSV992AIDT delivers 5× lower input offset for DC-critical sensor interfaces; versus TSV912AIST, it provides 2.5× higher bandwidth at only +37% supply current, making it optimal for medium-speed precision analog front-ends.

FAQ
Can TSV992AIDT be used in unity-gain buffer configuration?
No - the TSV992AIDT is not unity-gain stable. Per DS4975 Section 5.1, it requires minimum closed-loop gain of 4 (non-inverting) or –3 (inverting) for phase margin ≥ 45°. Using it as a follower without external compensation risks oscillation. Stability can be achieved by adding a 10–47 Ω series resistor at the output or a feedback capacitor across Rf in inverting configurations.
What is the maximum capacitive load the TSV992AIDT can drive without instability?
The TSV992AIDT remains stable with up to 100 pF capacitive load when configured at gain ≥ 4 (non-inverting) or ≤ –3 (inverting), as verified in DS4975 Figure 8–9 and Table 3–5. Driving larger loads requires isolation via series resistor or feedback capacitor; layout parasitics must be minimized, and PCB decoupling (10 nF near VCC+/VCC−) is mandatory per Section 5.2.
Does the exposed pad on the SO8 package require connection?
No - the SO8 package used for TSV992AIDT does not feature an exposed thermal pad. That feature applies only to DFN8 2x2 and DFN6 variants (see DS4975 Sections 6.2–6.3). The SO8 variant has standard gull-wing leads; thermal dissipation relies on copper pour under pins 4 (VCC−) and 8 (VCC+), with Rthja = 125 °C/W per Table 1.
How does the 1 pA input bias current impact high-impedance sensor interfacing?
At 1 pA typical, the TSV992AIDT introduces <1 µV of voltage error across a 1 MΩ source impedance - critical for photodiode transimpedance amps or pH electrode buffers. This enables direct connection to >100 MΩ sources without guard rings or bias-current cancellation networks, preserving signal integrity in low-current biosensing applications.
