Product details

Overview

TSV632ID from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage operation (1.5 V to 5.5 V), delivering 880 kHz gain-bandwidth product at 60 µA supply current per channel, 800 µV max input offset voltage (A-grade), and 1 pA typical input bias current - ideal for precision sensor signal conditioning in battery-powered medical and portable instrumentation.

For engineers reviewing the TSV632ID datasheet, TSV632ID pinout, TSV632ID application, or TSV632ID equivalent, key selection criteria include its shutdown-capable dual-channel architecture (TSV633/TSV635 variants), EMI-hardened performance up to 2.4 GHz, rail-to-rail output swing within 35 mV of rails, and guaranteed stability driving 100 pF capacitive loads without external compensation.

Technical Context

The TSV632ID employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (V_CC– – 0.1 V to V_CC+ + 0.1 V) with no phase reversal. Its micropower design achieves 60 µA/channel ICC at 5 V while maintaining 0.25 V/µs min slew rate and 730 kHz min GBP across temperature (–40 °C to 125 °C).

EMI rejection is engineered via internal filtering: EMIRR reaches 92 dB at 1.8 GHz, and shutdown mode reduces total supply current to 5 nA typ (V_CC = 5 V), with 200 ns turn-on time and high-impedance output state - critical for power-gated analog front-ends in portable systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.5 V to 5.5 V - enables direct operation from single-cell Li-ion, NiMH, or coin-cell batteries without regulation.
Gain Bandwidth Product	880 kHz typ - supports stable unity-gain active filters and sensor amplification up to ~100 kHz bandwidth.
Input Offset Voltage	800 µV max (A-grade) - ensures ≤0.016% error in 5 V full-scale 12-bit ADC interfaces.
Input Bias Current	1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor nodes.
Output Swing	Within 35 mV of rails (RL = 10 kΩ) - maximizes dynamic range in low-voltage data acquisition systems.
EMI Rejection Ratio	92 dB at 1.8 GHz - suppresses cellular/WiFi interference in wearable medical monitors.
Shutdown Current	5 nA typ - extends battery life by >1000× vs active mode in intermittent-sampling applications.

Pinout & Package

TSV632ID is available in SO8 (Small Outline 8-pin) package per STMicroelectronics' official mechanical drawing (DocID15688 Rev 6, Section 5.5). The exposed pad is not electrically connected and may be left floating or tied to V_CC–.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Channel A)	High-impedance node accepting differential feedback signals; rail-to-rail common-mode range supports ground-referenced sensors.
2	Non-inverting Input (Channel A)	Accepts single-ended or buffered reference/sensor inputs; 1 pA bias current minimizes loading on high-Z sources.
3	Output (Channel A)	Capable of sourcing/sinking ≥40 mA at 5 V; rail-to-rail swing preserves headroom in low-voltage signal chains.
4	V_CC– (Ground)	Power return path; decoupling capacitor (10 nF) must be placed adjacent to this pin for stability.
5	Non-inverting Input (Channel B)	Dedicated second channel input; identical specs to Channel A enable matched dual-signal processing.
6	Inverting Input (Channel B)	Supports independent feedback networks; no crosstalk between channels per datasheet AC characterization.
7	Output (Channel B)	Independent output stage; can drive separate loads or be paralleled for higher output current (per application note AN4195).
8	V_CC+	Positive supply rail; accepts 1.5–5.5 V; internal ESD protection rated to 4 kV HBM.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full utilization of 1.5–5.5 V supply range - eliminates level-shifting circuitry in single-supply systems.
EMI-hardened architecture	92 dB rejection at 1.8 GHz prevents RF-induced offset drift in cellular-connected wearables and IoT edge nodes.
Guaranteed stability with 100 pF load	Eliminates need for external compensation components in active filter and ADC driver designs.
Narrow ICC dispersion (±17%)	Ensures consistent GBP (730–880 kHz) and SR (0.25–0.34 V/µs) across production lots - simplifies system-level timing margining.
Automotive qualification	AEC-Q100 Grade 2 (–40 °C to 105 °C) compliance supports use in cabin electronics and ADAS sensor interfaces.

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
TSV632IST	Same core specs but in MiniSO10 package with integrated shutdown pin (SHDN); 2.2 mV max V_io vs 0.8 mV for TSV632ID.	Required when system-level power gating of analog section is needed; MiniSO10 footprint allows denser layout than SO8.	Select TSV632IST if shutdown control is mandatory and board space permits MiniSO10; otherwise TSV632ID offers tighter offset and standard SO8 compatibility.
MCP6022-E/SN	Higher 1 MHz GBP but 100 µA/channel ICC; 2 mV max V_io; no EMI hardening; only qualified to industrial temp (–40 °C to 85 °C).	Suitable for non-automotive, non-medical applications where speed outweighs power/EMI requirements.	Choose MCP6022-E/SN only if 120 kHz additional bandwidth is critical and EMI immunity is not required - avoid in medical/wearable designs.

Compared with TSV632IST, TSV632ID trades shutdown capability for superior offset voltage (0.8 mV vs 2.2 mV) and standard SO8 footprint; versus MCP6022-E/SN, it delivers 40% lower quiescent current, automotive qualification, and proven 92 dB EMI rejection - making it optimal for safety-critical, battery-constrained, and RF-dense environments.

FAQ

What is the maximum capacitive load the TSV632ID can drive without oscillation?

The TSV632ID is specified to remain unity-gain stable with up to 100 pF capacitive load at the output, per datasheet Section 4.6 and Figure 22. Driving larger loads requires an external series resistor (e.g., 10–100 Ω) between the output and load capacitance to maintain phase margin above 45°, validated by bench testing and SPICE simulation using ST's macromodel.

Does the TSV632ID have a shutdown pin, and how is it controlled?

No, the TSV632ID does not include a shutdown pin. Shutdown functionality is only available in the TSV633 and TSV635 variants (dual and quad with SHDN). The TSV632ID is a dual-channel op-amp without power-gating capability - all channels operate continuously when powered. For shutdown requirement, select TSV632IST (MiniSO10) or TSV633ID (SO8 with SHDN).

Can the TSV632ID operate from a 1.5 V supply, and what performance is guaranteed?

Yes, the TSV632ID operates down to 1.5 V supply, with full electrical specifications guaranteed across –40 °C to 125 °C. At 1.5 V, it delivers 700 kHz min GBP, 0.2 V/µs min slew rate, and rail-to-rail I/O - confirmed in Tables 4–7 and Figures 2–6 of the datasheet. Performance remains stable across the entire 1.5–5.5 V range.

Is the TSV632ID pin-compatible with other dual op-amps in SO8 packages like the LM358 or MCP6022?

No, the TSV632ID uses a non-standard SO8 pinout: Pin 1 = Inverting Input (A), Pin 2 = Non-inverting Input (A), Pin 3 = Output (A), Pin 4 = V_CC–, Pin 5 = Non-inverting Input (B), Pin 6 = Inverting Input (B), Pin 7 = Output (B), Pin 8 = V_CC+. This differs from LM358 (Pin 2/3 swapped) and MCP6022 (Pin 1/2/3/4 assigned to shutdown/control functions), requiring PCB redesign for replacement.
