Product details
Overview
TSV6292IST from STMicroelectronics is a dual micropower rail-to-rail input/output CMOS operational amplifier in MiniSO-8 package, delivering 1.3 MHz gain bandwidth at 29 µA supply current per amplifier, operating from 1.5 V to 5.5 V, and optimized for battery-powered sensor signal conditioning.
For engineers reviewing the TSV6292IST datasheet, TSV6292IST pinout, TSV6292IST application, or TSV6292IST equivalent, key selection criteria include guaranteed stability at gain ≥ +4, 800 µV max input offset voltage (A-version), 1 pA typical input bias current, and EMI-hardened performance up to 2.4 GHz.
Technical Context
The TSV6292IST uses complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) and rail-to-rail output swing (≤35 mV from rails into 10 kΩ). Its internal compensation ensures stability only at non-inverting gain ≥ +4 or inverting gain ≤ −3.
It features ultra-low power shutdown (5 nA typ), 4 kV HBM ESD rating, and extended temperature operation (−40 °C to +125 °C), with EMI rejection ratio exceeding 85 dB at 900 MHz and 92 dB at 1.8 GHz - critical for portable medical and industrial sensing environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 – 5.5 V: Enables direct integration into single-cell Li-ion (3.0–3.7 V), alkaline (1.5 V), or regulated 3.3/5 V systems without level-shifting. |
| Gain Bandwidth Product | 1.3 MHz typ at VCC = 5 V: Supports anti-aliasing filtering up to ~100 kHz and active low-pass designs with <1% gain error at 100 kHz. |
| Input Bias Current | 1 pA typ: Minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance amps). |
| Input Offset Voltage | 800 µV max (A version): Ensures ≤0.8 mV DC error in precision instrumentation amplifiers or bridge sensor front-ends. |
| Quiescent Current | 29 µA typ per op-amp: Allows >1-year battery life in coin-cell-powered devices (e.g., wearable biosensors) at 3 V with 10 µA system budget. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz: Suppresses cellular RF interference in portable diagnostics equipment without external shielding. |
| Common-Mode Range | VCC− − 0.1 V to VCC+ + 0.1 V: Accepts inputs beyond rails-critical for single-supply thermocouple or current-sense amplifier inputs. |
Pinout & Package
TSV6292IST is housed in an 8-pin MiniSO-8 package (ECOPACK® compliant, 3.0 × 3.0 mm body, 0.65 mm pitch), optimized for space-constrained portable PCBs with thermal resistance RthJA = 190 °C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | Accepts feedback or inverted signal path; requires impedance matching to non-inverting input for offset minimization. |
| 2 | Non-inverting Input (Amplifier 1) | High-impedance node (1 pA bias); must be guarded and decoupled to avoid noise coupling in sensor interfaces. |
| 3 | Output (Amplifier 1) | Rail-to-rail capable (≤35 mV from rails into 10 kΩ); drives ADC inputs or filters directly without level-shifting. |
| 4 | VCC− (Ground) | Reference return for both amplifiers; requires dedicated low-impedance ground plane and local 10 nF decoupling. |
| 5 | VCC+ (Supply) | 1.5–5.5 V input; connects to regulated LDO output; decoupling capacitor must be placed within 2 mm of this pin. |
| 6 | Output (Amplifier 2) | Independent output stage; supports dual-channel signal conditioning (e.g., differential sensor pair amplification). |
| 7 | Non-inverting Input (Amplifier 2) | Electrically isolated from Amp1 inputs; enables independent gain/offset tuning per channel in multi-sensor systems. |
| 8 | Inverting Input (Amplifier 2) | Matches Pin 1 characteristics; allows identical feedback network design across both channels for matched response. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 0–3.3 V ADC reference), eliminating level-shifters. |
| Micropower operation (29 µA/op) | Reduces total quiescent load to <60 µA for dual-channel use-critical for ISO 13849-compliant safety monitors with watchdog timers. |
| EMI-hardened architecture | Rejects 900 MHz and 1.8 GHz RF interference without external ferrites-validated per IEC 61000-4-3 up to 10 V/m. |
| Stable at gain ≥ +4 (non-inverting) | Eliminates need for external compensation capacitors in standard gain-of-5 sensor buffers, reducing BOM count and board area. |
| Extended temperature range (−40 to +125 °C) | Qualified for under-hood automotive cabin sensors and industrial motor control feedback loops without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6292IDT | Same electrical specs, but in SO-8 package (larger footprint, lower RthJA = 125 °C/W vs. 190 °C/W). | Better thermal performance in high-density industrial PCBs; less suitable for ultra-thin wearables. | Select when board space permits and thermal margin is constrained above 70 °C ambient. |
| TSV6392IST | Higher supply current (60 µA/op), 2.4 MHz GBP, unity-gain stable, same MiniSO-8 package. | Supports gain-of-1 configurations (e.g., voltage followers) and higher-bandwidth filtering (>200 kHz). | Choose when stability at G = 1 is required or when THD+N <0.01% at 10 kHz is critical for audio-grade sensing. |
Compared with TSV6292IDT, the TSV6292IST trades thermal efficiency for miniaturization-ideal for space-limited portable designs-while TSV6392IST offers higher speed and flexibility at double the quiescent power, making it suitable for applications demanding wider bandwidth or unity-gain stability.

FAQ
Is the TSV6292IST unity-gain stable?
No, the TSV6292IST is not unity-gain stable. It requires minimum non-inverting gain of +4 or inverting gain of −3 for stable operation, as confirmed by phase margin testing at 60° with 20 pF load and 10 kΩ feedback. For unity-gain applications, ST recommends the TSV6392IST or TSV622 series instead.
What is the maximum capacitive load the TSV6292IST can drive without oscillation?
The TSV6292IST is characterized for stability with up to 100 pF capacitive load when used in gain ≥ +4 configuration and driving a 10 kΩ resistive load. Driving >100 pF directly risks peaking or oscillation; a series resistor (≥100 Ω) between output and capacitance is required for larger loads per Figure 5–7 in the datasheet.
Does the TSV6292IST have a shutdown pin?
No, the TSV6292IST does not include a shutdown function. Shutdown capability is only present in the TSV6293 (dual with two SHDN pins) and TSV6295 (quad) variants. The TSV6292IST operates continuously when powered and has no logic-controlled disable feature.
Can the TSV6292IST operate from a 1.5 V supply?
Yes, the TSV6292IST is fully specified and functional down to 1.5 V supply voltage, with validated performance including 1.1 MHz GBP, 0.33 V/µs slew rate, and rail-to-rail input/output swing. Electrical characteristics tables confirm operation across 1.5–5.5 V, and Figures 2–4 explicitly characterize behavior at 1.5 V.
