Product details

Overview

TSH22IDT from STMicroelectronics is a dual bipolar operational amplifier designed for precision analog signal conditioning in industrial and automotive systems. It delivers 25MHz gain-bandwidth product, 15V/µs slew rate, ±1.5V to ±15V (or 3V–30V single-supply) operation, 14nV/√Hz input voltage noise, and guaranteed no phase inversion - enabling robust comparator and active filter use in rail-to-rail–compatible front-ends.

For engineers reviewing the TSH22IDT datasheet, TSH22IDT pinout, TSH22IDT application, or TSH22IDT equivalent, key selection criteria include unity-gain stability under 30V supply, latch-up immunity at +125°C, output swing within 1.8V of rails, CMRR ≥80dB, and SPICE macromodel availability for transient simulation of high-speed closed-loop designs.

Technical Context

The TSH22IDT employs a bipolar input stage with complementary NPN/PNP differential pairs to eliminate phase inversion during large-signal overdrive - critical for comparator-mode operation. Its internal compensation ensures unity-gain stability across full supply range (3V–30V) without external components.

It features matched dual channels with 120dB channel separation (20Hz–20kHz), low 2µV/°C input offset drift, and rail-sensing common-mode input range (V_CC− to V_CC+ − 1.8V), supporting accurate single-supply sensor interfacing and active filtering in mixed-signal control loops.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain-Bandwidth Product	25 MHz - supports stable closed-loop amplification up to 100 kHz at AV = +100 without peaking
Slew Rate	15 V/µs - enables ≤2 µs response to 50 mV overdrive in comparator mode with TTL/CMOS-compatible output levels
Input Voltage Noise	14 nV/√Hz @ 1 kHz - preserves SNR in low-level transducer signal chains (e.g., strain gauge, thermocouple)
Common-Mode Range	V_CC− to V_CC+ − 1.8 V - allows direct interface to 0–5 V sensors on +5 V single supply
Output Swing	±13.9 V @ ±15 V supply (RL = 2 kΩ) - delivers >92% rail utilization for dynamic range maximization
ESD Tolerance	2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level ESD robustness in industrial environments
Operating Temp	−40°C to +125°C - qualified for under-hood automotive and factory-floor PLC applications

Pinout & Package

Package: SO8 (Plastic Micropackage), 8-pin surface-mount, 1.27 mm pitch, body size 4.9 × 6.0 × 1.75 mm (D × E × A).

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier 1)	Differential node for negative feedback configuration; accepts common-mode voltages down to V_CC−
2	Non-inverting Input (Amplifier 1)	High-impedance reference node; supports DC-coupled sensor biasing
3	Output (Amplifier 1)	Class-AB output stage capable of ±37 mA short-circuit current; drives 2 kΩ loads to ±13.9 V
4	Positive Supply (V_CC+)	Accepts 3 V to 30 V (single) or +1.5 V to +15 V (dual); decoupling required within 10 mm
5	Negative Supply (V_CC−)	Accepts 0 V to −30 V (single) or −1.5 V to −15 V (dual); shared return for both amplifiers
6	Inverting Input (Amplifier 2)	Electrically isolated from Amp1; 120 dB channel separation prevents crosstalk in dual-channel filters
7	Non-inverting Input (Amplifier 2)	Independent high-Z input; supports separate sensor inputs without interaction
8	Output (Amplifier 2)	Matched performance to Pin 3; identical slew rate, noise, and drive capability

Key Features

Feature	Design Value
No phase inversion	Guaranteed correct logic polarity during large differential input transients - eliminates false triggering in comparator applications
Latch-up immunity	Withstands I/O stress beyond absolute maximum ratings without destructive latch-up - essential for noisy industrial bus interfaces
Unity-gain stable	Operates stably at AV = +1 with no external compensation - simplifies active filter and buffer design
SPICE macromodel included	Validated behavioral model (1993 Standard Linear ICs) supports accurate AC/transient simulation of closed-loop bandwidth and settling
Low input bias current mismatch	Typical I_IB = 100–650 nA with <10% channel-to-channel variation - minimizes offset error in high-impedance photodiode amplifiers

Applications

IC Role / Device Role / Timing Role: High-speed dual op-amp configured as independent comparators with sub-2 µs propagation delay.

Use Value: No phase inversion ensures reliable state transitions even during fast battery dip/recovery events in 12 V vehicle systems.

Audio Pre-amplifier Stage

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual high-speed operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL082CDR	Lower GBP (3 MHz), higher input noise (18 nV/√Hz), no guaranteed no-phase-inversion behavior	Not suitable for comparator use; requires external clamping for rail-to-rail input	Select only for cost-sensitive, low-bandwidth linear amplification where phase inversion risk is mitigated by system design
LM358DT	Slower slew rate (0.6 V/µs), lower GBP (1 MHz), wider input offset (7 mV max), not specified for >85°C operation	Restricted to commercial-temperature consumer electronics; cannot replace TSH22IDT in automotive or industrial thermal environments	Use only in benign ambient conditions (<70°C) with relaxed speed/noise requirements and no comparator functionality needed

Compared with TL082CDR and LM358DT, the TSH22IDT uniquely combines 25 MHz bandwidth, phase-inversion immunity, and −40°C to +125°C qualification - making it the sole option among the three for high-reliability comparator and wide-temperature analog front-ends.

FAQ

Is the TSH22IDT unity-gain stable with capacitive loads?

Yes - the TSH22IDT is internally compensated for unity-gain stability up to 100 pF capacitive load at the output when driving a 2 kΩ load, as verified in the datasheet's small-signal response plots (TSH22 8/11). For >100 pF, a series resistor (≥100 Ω) between amplifier output and capacitor is recommended to maintain phase margin above 40°.

Can TSH22IDT operate from a single 3.3 V supply?

Yes - the TSH22IDT supports single-supply operation from 3 V to 30 V. At V_CC = +3.3 V / GND, the common-mode input range extends from 0 V to 1.5 V, and output swing reaches ≥2.6 V (high) and ≤0.3 V (low) into 10 kΩ, enabling compatibility with 3.3 V logic and low-voltage sensors.

What is the maximum junction temperature during continuous operation?

The absolute maximum junction temperature is +150°C (T_j), with derating applied above +70°C ambient. At T_amb = +125°C and P_D = 500 mW (max), the thermal resistance θ_JA of the SO8 package (125°C/W) limits safe dissipation to ~400 mW - consistent with the datasheet's P_tot rating and thermal design guidance on page 2.

Does TSH22IDT include ESD protection on all pins?

Yes - the TSH22IDT features integrated HBM ESD protection rated at 2 kV on all pins (input, output, and supply), as explicitly stated in the "ESD TOLERANCE" specification on page 1. This protection is process-integrated and does not require external TVS diodes for basic board-level ESD compliance.
