Product details

Overview

TSH24IDT from STMicroelectronics is a quad bipolar operational amplifier designed for precision analog signal conditioning in industrial and automotive systems. It delivers 25 MHz gain-bandwidth product, 15 V/µs slew rate, ±1.5V to ±15V (or 3V–30V single-supply) operation, 14 nV/√Hz input voltage noise, and guaranteed no phase inversion - enabling robust comparator and active filter use in rail-to-rail–compatible circuits.

For engineers reviewing the TSH24IDT datasheet, TSH24IDT pinout, TSH24IDT application, or TSH24IDT equivalent, key selection criteria include unity-gain stability, latch-up immunity, ESD tolerance (2 kV), common-mode input range extending to V_CC−1.8 V, and validated SPICE macromodel support for pre-layout simulation.

Technical Context

The TSH24IDT integrates four independent high-speed bipolar op-amps with matched internal transistor pairs, enabling precise differential amplification and fast settling in multi-channel sensor interfaces. Its input stage avoids phase inversion up to ±36 V differential input, and its output stage delivers ±40 mA drive capability into 2 kΩ loads with <0.2 V saturation voltage at 5 V supply.

It operates across −40°C to +125°C with input offset drift of only 2 µV/°C and maintains >100 dB CMRR and SVRR over full temperature and supply range. The device achieves 34 MHz closed-loop bandwidth at AV = +1 with 100 pF capacitive load, supporting stable operation in active filters and high-fidelity audio front-ends.

Pinout & Package

Package: SO14 (Plastic Micropackage), 14-pin small outline, surface-mount, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amp 1)	Differential input node for first op-amp; accepts signals referenced to common-mode range up to V_CC+−1.8 V.
2	Non-inverting Input (Amp 1)	High-impedance input (I_IB = 100–650 nA) for reference or sensor signal routing without loading.
3	Output (Amp 1)	Class-AB output capable of ±40 mA sink/source; VOH ≥3.7 V / VOL ≤0.2 V at 5 V supply into 2 kΩ.
4	Positive Supply (V_CC+)	Primary power rail; supports 3–30 V single or positive side of dual supply; decoupling required within 5 mm.
5	Negative Supply (V_CC−)	Ground or negative rail; enables true dual-supply operation down to −15 V; must be tied to system ground in single-supply mode.
6	Inverting Input (Amp 2)	Independent input for second amplifier; electrically isolated from Amp 1 with >120 dB channel separation at audio frequencies.
7	Non-inverting Input (Amp 2)	Matched bias current and offset specs to Amp 1; supports synchronous multi-channel signal processing.
8	Output (Amp 2)	Identical drive strength and noise performance as Amp 1; usable in parallel configurations for increased output current.
9	Inverting Input (Amp 3)	Third amplifier input; shares same thermal and process tracking as other channels for matched gain error.
10	Non-inverting Input (Amp 3)	Enables three-stage active filtering or cascaded gain stages with minimal inter-channel crosstalk.
11	Output (Amp 3)	Supports independent feedback networks; output swing extends to within 1.1 V of either rail at ±15 V supply.
12	Inverting Input (Amp 4)	Fourth channel input optimized for low-noise pre-amplification; benefits from shared substrate noise isolation.
13	Non-inverting Input (Amp 4)	Allows simultaneous monitoring of four sensor outputs (e.g., bridge-based strain gauges) with matched DC accuracy.
14	Output (Amp 4)	Final output stage with identical AC performance; usable as reference buffer or comparator output driver.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad bipolar operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM324DT	Lower GBP (1.2 MHz), higher input offset (7 mV), no phase inversion guarantee, 0.6 V/µs slew rate.	Acceptable for DC-coupled sensor buffers but unsuitable for >10 kHz active filters or comparator use.	Select when cost sensitivity outweighs speed/noise requirements and phase inversion risk is mitigated externally.
TL084CDT	JFET input (lower I_IB = 30 pA), higher GBP (3 MHz), no specified phase inversion immunity, 13 V/µs slew rate.	Better for high-impedance sources (e.g., photodiodes), but lacks latch-up immunity and ESD robustness for industrial field I/O.	Prefer for low-input-bias applications where bipolar noise floor is not limiting and supply rails exceed ±12 V.

Compared with LM324DT and TL084CDT, the TSH24IDT uniquely combines 25 MHz bandwidth, guaranteed no phase inversion, 2 kV ESD tolerance, and −40°C to +125°C operation - making it the only option qualified for high-reliability, multi-channel, mixed-signal industrial control nodes requiring both precision and robustness.

FAQ

Is TSH24IDT pin-compatible with standard SO14 quad op-amps like LM324 or TL084?

Yes - TSH24IDT uses the industry-standard SO14 pinout (1 = In−, 2 = In+, 3 = Out, 4 = V+, 5 = V−, etc.), matching LM324DT and TL084CDT. All four amplifiers share identical terminal mapping, enabling drop-in replacement in existing PCB layouts without redesign. However, verify layout decoupling and thermal relief per ST's recommended footprint for SO14.

Does TSH24IDT support true single-supply operation down to 3 V?

Yes - TSH24IDT operates from 3 V to 30 V single supply, with common-mode input range extending from V_CC− (GND) to V_CC+−1.8 V and output swing to within 1.1 V of either rail at ±15 V. At 3 V supply, it delivers usable output swing from 0.15 V to 2.85 V into 10 kΩ, confirmed by electrical characterization in the datasheet.

What is the maximum capacitive load the TSH24IDT can drive while remaining stable?

TSH24IDT is unity-gain stable with up to 100 pF capacitive load, as verified by phase margin measurements (40° at CL = 100 pF). Driving >100 pF requires external compensation (e.g., series resistor at output) or reduced closed-loop gain. Stability data is provided in Figures 8–9 of the official datasheet under "Small Signal Response" and "Closed Loop Bandwidth" plots.

Can TSH24IDT be used as a comparator without external hysteresis?

Yes - TSH24IDT is explicitly characterized for comparator use due to its lack of phase inversion, fast transition time (~2 µs at 50 mV overdrive), and logic-compatible output levels (VOH ≥3.7 V, VOL ≤0.2 V at 5 V supply). However, for noise immunity in slow-moving inputs, external hysteresis is still recommended - the device itself does not integrate Schmitt-trigger functionality.
