Product details
Overview
TSV6290ICT from STMicroelectronics is a single-channel micropower CMOS operational amplifier with rail-to-rail input and output, 1.3 MHz gain bandwidth product, 29 µA typical supply current, and integrated shutdown control. It operates from 1.5 V to 5.5 V and supports extended temperature range (–40 °C to +125 °C), making it suitable for precision signal conditioning in ultra-low-power battery-powered sensor interfaces.
For engineers reviewing the TSV6290ICT datasheet, TSV6290ICT pinout, TSV6290ICT application, or TSV6290ICT equivalent, key selection considerations include its minimum stable gain requirement (G ≥ 4), shutdown logic thresholds (VIH = 4.5 V at VCC = 5 V), rail-to-rail input common-mode range (–0.1 V to VCC + 0.1 V), and guaranteed phase reversal immunity - critical for medical instrumentation and portable analog front-ends.
Technical Context
The TSV6290ICT uses complementary PMOS/NMOS input stages enabling true rail-to-rail input operation across –0.1 V to VCC + 0.1 V, with no phase reversal. Its internal compensation requires minimum closed-loop gain of 4 (non-inverting) or |G| ≥ 3 (inverting) for stability with 100 pF load.
It features a dedicated SHDN pin that places the output in high-impedance state when pulled low (≤0.5 V), reducing supply current to ≤1.5 µA at 125 °C. Turn-on/turn-off times are specified at 300 ns and 30 ns respectively under 5 kΩ load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion, NiMH, or alkaline batteries without regulation. |
| Supply Current (Typ.) | 29 µA - extends battery life in always-on sensor nodes and wearable devices. |
| Gain Bandwidth Product | 1.3 MHz - supports bandwidth-critical active filtering up to ~100 kHz with G = 10. |
| Input Offset Voltage (A version) | 0.8 mV max - ensures <10 µV error in 12-bit ADC front-end with 3.3 V reference. |
| Rail-to-Rail I/O | Input: –0.1 V to VCC + 0.1 V; Output swing to within 35 mV of rails @ 10 kΩ - maximizes dynamic range in low-voltage systems. |
| Shutdown Current | ≤1.5 µA @ 125 °C - maintains ultra-low quiescent power during system sleep modes. |
| ESD Robustness | 4 kV HBM - eliminates need for external ESD protection in handheld medical probes and industrial sensors. |
Pinout & Package
TSV6290ICT is supplied in SC70-6 package (2.0 × 2.1 mm, 0.65 mm pitch), optimized for space-constrained portable designs. Pin mapping is validated per STMicroelectronics DocID17117 Rev 2, Figure 27 and Table 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | Accepts signals from –0.1 V to VCC + 0.1 V; bias current ≤1 pA minimizes leakage errors in high-Z sensor interfaces. |
| 2 (IN–) | Inverting input | Differential pair node; offset voltage drift ≤2 µV/°C ensures thermal stability in uncalibrated field deployments. |
| 3 (V–) | Negative supply | Ground reference for single-supply operation; supports rail-to-rail input down to V– – 0.1 V. |
| 4 (SHDN) | Shutdown control | Active-low logic input; VIH = 4.5 V @ VCC = 5 V ensures compatibility with 3.3 V GPIO without level-shifting. |
| 5 (OUT) | Amplifier output | Drives loads ≥5 kΩ; high-Z state during shutdown prevents loading of downstream circuitry. |
| 6 (V+) | Positive supply | Accepts 1.5–5.5 V; internal regulation not required - simplifies power architecture in multi-rail systems. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 29 µA typical ICC enables >1-year battery life in coin-cell-powered IoT endpoints (e.g., CR2032 @ 220 mAh). |
| Rail-to-rail input stage | Extended common-mode range (–0.1 V to VCC + 0.1 V) allows direct interfacing with resistive sensors biased at mid-supply. |
| Guaranteed phase reversal immunity | Eliminates output latch-up risk when input exceeds rails - critical for ECG electrode amplifiers and thermistor circuits. |
| Low input bias current | 1 pA typical enables accurate measurement of high-impedance sources (>100 MΩ), such as pH electrodes and piezoelectric sensors. |
| Stable shutdown transition | 300 ns turn-on / 30 ns turn-off ensures precise timing control in duty-cycled sensor acquisition systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6291ICT | No shutdown pin; SOT23-5/SC70-5 package; identical electrical specs except missing SHDN functionality. | Suitable where continuous operation is acceptable and board space permits larger SOT23-5 footprint. | Select when shutdown control is unnecessary and cost optimization favors simpler variant. |
| TSV6390ICT | 60 µA ICC, 2.4 MHz GBP, unity-gain stable, same SC70-6 package. | Better for higher-speed active filters or unity-gain buffers where TSV6290ICT's minimum gain constraint is limiting. | Choose when bandwidth >1.3 MHz or G = 1 configuration is required, accepting 2× higher current draw. |
Compared with TSV6291ICT, TSV6290ICT adds system-level power control via SHDN but requires careful gain planning; versus TSV6390ICT, it trades bandwidth and unity-gain stability for 52% lower quiescent current - decisive in multi-year battery applications.

FAQ
What is the minimum closed-loop gain required for stable operation of TSV6290ICT?
The TSV6290ICT is not unity-gain stable and requires minimum closed-loop gain of 4 in non-inverting configuration or |G| ≥ 3 in inverting configuration when driving 100 pF capacitive loads. This is confirmed in Section 5.6 of the datasheet and Table 8, which specifies "Minimum gain for stability" as 11 for CL = 100 pF in inverting mode. Operating below this threshold risks peaking or oscillation.
Does TSV6290ICT support true rail-to-rail input at 1.5 V supply?
Yes - the input common-mode range extends from (V–) – 0.1 V to (V+) + 0.1 V across the full 1.5–5.5 V supply range, verified in Table 2 (Vicm = VCC/2 ± 0.1 V) and Section 5.2. At 1.5 V, this means inputs can swing from –0.1 V to +1.6 V, enabling direct interface with sensors referenced to ground or mid-supply without level-shifting.
How does the shutdown function affect output behavior?
When SHDN is pulled low (≤0.5 V), the amplifier output enters high-impedance state with leakage ≤1 nA (Table 4), isolating downstream circuitry. The output does not float - it is actively disabled. This is distinct from output disable in comparators or digital buffers and is validated in Figure 20–23 for turn-on/turn-off timing under 5 kΩ load.
Is TSV6290ICT compatible with SC70-6 footprints from other manufacturers?
Yes - mechanical dimensions match JEDEC standard MO-203AA (SC70-6), with 0.65 mm pitch, 2.0 × 2.1 mm body, and coplanar lead geometry per Table 12. ST's ECOPACK® compliance ensures solderability and thermal performance consistency, and footprint compatibility is confirmed by Digi-Key and Mouser landing pattern references for SC70-6 packages.
