Product details
Overview
TSV7723IST from STMicroelectronics is a dual, rail-to-rail output operational amplifier with shutdown control, optimized for high-accuracy low-side current sensing and photodiode amplification. It delivers 22 MHz gain bandwidth, 50 µV typical input offset voltage, 2 pA typical input bias current, and operates from 1.8 V to 5.5 V single supply - enabling precision signal conditioning in automotive sensor interfaces and strain gauge front-ends.
For engineers reviewing the TSV7723IST datasheet, TSV7723IST pinout, TSV7723IST application, or TSV7723IST equivalent, this device is selected for its combination of ultra-low input bias current, rail-to-rail output swing, shutdown-enabled power management, and guaranteed performance across –40°C to +125°C for automotive-grade designs.
Technical Context
The TSV7723IST integrates two independent high-speed op-amps with dedicated enable inputs (EN1/EN2) that place each channel into sub-60 nA shutdown mode when pulled to VCC–. Its input stage is optimized for common-mode voltages near ground (VCC– – 0.1 V), supporting accurate low-side shunt measurement without level-shifting circuitry.
Each amplifier features unity-gain stability with 47 pF capacitive load, 11 V/µs slew rate, and 7 nV/√Hz input voltage noise at 10 kHz - enabling fast settling (270 ns to 0.1%) and high-fidelity amplification of weak sensor signals while maintaining DC precision via 200 µV max input offset voltage over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 22 MHz - supports closed-loop bandwidth up to ~20 MHz in unity-gain configuration for high-frequency sensor signal conditioning. |
| Input Offset Voltage | 50 µV typ., 200 µV max - enables <100 µV error in 10 mΩ shunt-based current sensing at 1 A full scale. |
| Input Bias Current | 2 pA typ. - allows direct connection to photodiodes and high-impedance sensors without significant current-induced error. |
| Supply Voltage Range | 1.8 V to 5.5 V - compatible with Li-ion, 3.3 V, and 5 V systems; fully specified at all three rails. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs or downstream stages without headroom loss. |
| Shutdown Current | 60 nA typ. per channel - reduces total system quiescent current by >99% when unused channels are disabled. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial environments. |
| Input Noise Density | 7 nV/√Hz at 10 kHz - preserves SNR in low-amplitude, wideband transducer signals such as strain gauges. |
Pinout & Package
TSV7723IST is housed in MiniSO10 package (3.0 mm × 4.4 mm, 0.65 mm pitch), a surface-mount SO-style 10-pin variant with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail capable; drives ADC input or next-stage buffer directly. |
| 2 | IN1− | Inverting input 1 - used for differential or inverting configurations; matched to IN1+ for CMRR >74 dB. |
| 3 | IN1+ | Non-inverting input 1 - low-offset, low-bias node; supports common-mode down to VCC− – 0.1 V. |
| 4 | VCC− | Negative supply - reference for both amplifiers and EN logic; connects to system ground in single-supply use. |
| 5 | EN1 | Enable 1 - active-high logic; pulls to VCC− to disable Amp1 and reduce ICC to 60 nA. |
| 6 | EN2 | Enable 2 - independent control for Amp2; allows asymmetric power gating in multi-channel systems. |
| 7 | IN2+ | Non-inverting input 2 - electrically identical to IN1+; supports dual-sensor or differential pair topologies. |
| 8 | IN2− | Inverting input 2 - matched to IN2+; enables simultaneous low-side current monitoring on two circuits. |
| 9 | OUT2 | Amplifier 2 output - fully independent; no crosstalk (CS = 120 dB at 1 kHz). |
| 10 | VCC+ | Positive supply - accepts 1.8–5.5 V; supplies both amps and internal bias networks. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 2 pA typ. - eliminates voltage error across high-value feedback resistors in photodiode transimpedance amplifiers. |
| Low input offset voltage drift | ±4 µV/°C - limits total offset shift to <3.4 mV over –40°C to +125°C, critical for uncalibrated automotive sensors. |
| Independent shutdown control | Dual EN pins - enables per-channel power gating for dynamic power scaling in battery-powered multi-sensor nodes. |
| Rail-to-rail output with low saturation | VOL/VOL = 15 mV typ. at 5 V - preserves >99% of ADC input range even at full-scale output swing. |
| High CMRR at low common-mode | 76 dB min. at Vicm = 0 V - ensures accuracy in low-side shunt applications where input common-mode sits near ground. |
| EMI robustness | EMIRR >70 dB measured from 400 MHz–2.4 GHz - suppresses RF rectification artifacts in noisy automotive environments. |
Applications
| Automotive Low-Side Current Sensing | Photodiode Signal Amplification |
|---|---|
Use Scenario: Monitoring battery discharge current in 12 V automotive ECUs using a 500 µΩ shunt resistor. IC Role / Device Role / Timing Role: Precision differential amplifier with input referenced to ground, rejecting common-mode noise from alternator ripple.

IC Role / Device Role / Timing Role: Transimpedance amplifier with ultra-low input bias current to avoid signal attenuation and dark-current distortion. Use Value: 2 pA bias current prevents >2% gain error at 100 pA input; 22 MHz GBW supports >100 kHz optical modulation bandwidth. |
| Strain Gauge Bridge Interface | Industrial Sensor Signal Conditioning |
Use Scenario: Amplifying mV-level output from a 350 Ω Wheatstone bridge in a load cell within a factory automation system. IC Role / Device Role / Timing Role: Instrumentation-grade front-end with rail-to-rail output driving a 16-bit SAR ADC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, shutdown-enabled, precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV792IDT | 50 MHz GBW, no shutdown, higher supply (up to 5.5 V), same MiniSO8 package | Better for wideband filtering or active anti-aliasing; lacks per-channel power control | Select when bandwidth >30 MHz is required and shutdown is unnecessary. |
| TSB7192IPT | 22 MHz GBW, 36 V supply, no shutdown, SO8 package, higher offset (300 µV max) | Suitable for industrial 24 V systems; not automotive qualified | Select for high-voltage sensor interfaces where extended supply range outweighs offset and temp grade trade-offs. |
Compared with TSV7723IST, TSV792IDT trades shutdown capability for 2.3× higher bandwidth but sacrifices automotive qualification and low-VOS optimization; TSB7192IPT retains GBW and adds high-voltage tolerance but increases offset and removes temperature grade - making TSV7723IST uniquely balanced for automotive low-side sensing with dynamic power control.

FAQ
What is the minimum supply voltage for reliable operation of TSV7723IST?
The TSV7723IST is fully specified and guaranteed to operate down to 1.8 V supply voltage across the full –40°C to +125°C temperature range. At 1.8 V, it maintains 21 MHz gain bandwidth, 1.7 mA per-channel supply current, and 76 dB CMRR - enabling compatibility with modern ultra-low-power microcontrollers and battery-backed systems.
How does the shutdown feature affect output leakage and turn-on time?
In shutdown mode (ENx = VCC−), output leakage is limited to 50 pA typ. at 25°C and 15 nA max. over temperature, preserving signal integrity in high-impedance nodes. Turn-on time is 2 µs (when one channel is already active) or 7 µs (cold start), ensuring rapid reactivation for burst-mode sensing without compromising system responsiveness.
Can TSV7723IST drive a 47 pF capacitive load in unity-gain configuration without external compensation?
Yes - the TSV7723IST is unity-gain stable with up to 47 pF capacitive load, as confirmed by phase margin ≥42° and overshoot <5% in closed-loop step response. For loads >47 pF, a 10–22 Ω isolation resistor in series with the output restores stability without degrading DC accuracy or bandwidth significantly.
Is the input common-mode range truly extended to the negative rail?
Yes - the input common-mode voltage range extends to VCC− – 0.1 V, verified across temperature and supply voltage. This allows direct connection to ground-referenced shunts and photodiodes without level-shifting, and is central to its optimization for low-side current measurement where Vicm ≈ 0 V.
