Product details

Overview

TSV732IST from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, high-accuracy signal conditioning in battery-powered systems. It delivers 200 µV max input offset voltage, 60 µA supply current per channel at 5 V, and 900 kHz gain bandwidth product, operating from 1.5 V to 5.5 V across –40 °C to +125 °C - enabling precision sensor front-ends in portable medical devices.

For engineers reviewing the TSV732IST datasheet, TSV732IST pinout, TSV732IST application, or TSV732IST equivalent, key selection criteria include micropower operation under 1.8 V, EMI-hardened performance at 41–66 dB (400–2400 MHz), rail-to-rail I/O swing within 40 mV/75 mV of rails, and guaranteed long-term stability with <0.7 µV/month drift at 25 °C.

Technical Context

The TSV732IST implements a CMOS input stage with 1 pA typical input bias current and rail-to-rail common-mode input range (VCC− −0.1 V to VCC+ +0.1 V), enabling direct interfacing with low-output-impedance sensors and ADC references. Its internal differential voltage limiter clamps input differential voltage to ±0.5 V, enhancing robustness against transient overvoltage.

It features a unity-gain-stable architecture with 48° phase margin and 15 dB gain margin at 5 V, supporting stable closed-loop configurations up to 100 pF capacitive load. The 0.35 V/μs slew rate and 7 µVpp 0.1–10 Hz noise support low-frequency precision applications without oscillation or settling degradation.

Key Specifications

Parameter	Value and Actual Design Meaning
Input offset voltage	200 µV max at 25 °C - enables <0.1% error in 200 mV full-scale sensor outputs without calibration
Supply current per channel	60 µA typ. at 5 V - supports >10-year battery life in coin-cell-powered IoT nodes
Gain bandwidth product	900 kHz typ. - sufficient for anti-aliasing filters up to ~100 kHz with unity-gain stability
Input bias current	1 pA typ. - preserves signal integrity when amplifying high-impedance sources (>100 MΩ)
Rail-to-rail output swing	Within 40 mV of VCC+ and 75 mV of VCC− at 10 kΩ load - maximizes dynamic range into 12-bit ADCs
EMI rejection ratio	66 dB at 2.4 GHz - suppresses cellular/Wi-Fi interference in handheld diagnostic equipment
Operating temperature	–40 °C to +125 °C - qualified for under-hood automotive and industrial edge-sensor deployments

Pinout & Package

The TSV732IST is housed in an 8-pin MiniSO-8 package (3.9 mm × 4.9 mm, 1.75 mm height) with exposed pad for thermal enhancement and ESD robustness. Pin 1 is marked by a dot; pins are numbered counterclockwise.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT A)	Channel A output	Delivers rail-to-rail buffered signal; drives 10 kΩ load to within 40 mV/75 mV of rails
2 (–IN A)	Channel A inverting input	Accepts differential signals up to ±0.5 V; protected by internal clamp diodes
3 (+IN A)	Channel A non-inverting input	Supports common-mode range from VCC− −0.1 V to VCC+ +0.1 V
4 (VCC−)	Negative supply	Ground reference for single-supply operation; connects to system GND
5 (+IN B)	Channel B non-inverting input	Independent high-impedance node; 1 pA bias current minimizes loading on sensor bridges
6 (–IN B)	Channel B inverting input	Matches Channel A electrical behavior; supports matched feedback networks
7 (OUT B)	Channel B output	Electrically identical to OUT A; enables dual-channel signal processing in one footprint
8 (VCC+)	Positive supply	Accepts 1.5–5.5 V; internal regulation ensures stable biasing across voltage range

Key Features

Feature	Design Value
EMI-hardened architecture	41–66 dB rejection from 400 MHz to 2.4 GHz - prevents RF rectification-induced DC errors in noisy environments
Low long-term V_OS drift	0.7 µV/month typical - reduces recalibration frequency in field-deployed instrumentation
Rail-to-rail input and output	V_ICM = VCC− −0.1 V to VCC+ +0.1 V; V_OH/V_OL ≤ 75/40 mV - preserves full ADC code utilization
High ESD tolerance	4 kV HBM - withstands handling and board-level electrostatic discharge without latch-up
Extended temperature operation	Specified from –40 °C to +125 °C - supports automotive cabin and industrial motor-control ambient conditions

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual micropower precision op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV732IYDT	Same die in DFN8 2×2 package (2.0 mm × 2.0 mm); no exposed pad; 120 °C/W R_thJA	Better suited for space-constrained PCBs where thermal mass is limited and ambient temperature stays <85 °C	Select for ultra-dense layouts; verify thermal derating if operating above 85 °C ambient
MCP6022-E/SN	Higher 100 µA supply current; 1 mV V_OS max; 10 MHz GBP; not EMI-hardened	Preferred where speed >100 kHz or cost sensitivity outweighs battery life and RF immunity requirements	Choose only if 900 kHz GBP is insufficient and EMI environment is controlled (e.g., shielded enclosures)

Compared with TSV732IST, the TSV732IYDT offers identical electrical performance in a smaller footprint but reduced thermal capability, while the MCP6022-E/SN trades micropower and EMI resilience for higher speed and lower cost - making the TSV732IST optimal for battery longevity and harsh RF environments.

FAQ

What is the maximum capacitive load the TSV732IST can drive stably?

The TSV732IST maintains unity-gain stability with up to 100 pF capacitive load, as verified in the datasheet's Bode and closed-loop gain diagrams. Driving larger loads requires external isolation resistance (e.g., 10–100 Ω in series with the output) to preserve phase margin and prevent peaking or oscillation - especially critical in active filter and ADC driver applications.

Does the TSV732IST support true single-supply operation down to 1.5 V?

Yes - the TSV732IST is fully specified from 1.5 V to 5.5 V, with all key parameters (including 200 µV V_OS, 60 µA I_CC, and rail-to-rail I/O) guaranteed across this range. At 1.5 V, it delivers usable gain bandwidth (~700 kHz) and output swing within 80 mV of rails, enabling direct integration with Li-ion or alkaline primary cells without LDO regulation.

How does the EMI hardening work, and what frequencies does it cover?

The TSV732IST integrates on-die RF filters and layout-level shielding that attenuate RF energy before it reaches sensitive input stages. Measured EMI rejection ratio is 41 dB at 400 MHz, 51 dB at 900 MHz, 61 dB at 1.8 GHz, and 66 dB at 2.4 GHz - directly addressing interference from GSM, Bluetooth, Wi-Fi, and ISM-band transceivers commonly found in portable electronics.

Is the MiniSO-8 package RoHS-compliant and lead-free?

Yes - the TSV732IST MiniSO-8 package meets RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination finish. It complies with JEDEC J-STD-020 moisture sensitivity level (MSL) 1, allowing unlimited floor life at ≤30 °C/60% RH and reflow peak temperatures up to 260 °C per JEDEC standard.
