Product details

Overview

TS274IDT from STMicroelectronics is a high-performance CMOS quad operational amplifier designed for single- or dual-supply operation across industrial temperature range (−40°C to +125°C). It delivers 3.5 MHz gain bandwidth, 5.5 V/µs slew rate, 1 mA per amplifier supply current, rail-to-ground output swing, and 65–80 dB common-mode rejection - enabling precision signal conditioning in sensor interfaces and analog front-ends.

For engineers reviewing the TS274IDT datasheet, TS274IDT pinout, TS274IDT application, or TS274IDT equivalent, key selection criteria include input offset voltage (≤10 mV), low input bias current (≤300 pA), unity-gain stability with capacitive loads, and SO-14/TSSOP-14 packaging compatibility for space-constrained industrial control and instrumentation designs.

Technical Context

The TS274IDT implements a CMOS input stage with silicon-gate process technology, delivering ultra-low input bias current (1–300 pA) and minimal drift over temperature. Its two-stage architecture includes internal compensation for unity-gain stability and phase margin ≥40° with 100 pF capacitive load.

It operates from 3 V to 16 V supply, supports common-mode input range from ground to V_CC − 1.5 V, and provides rail-to-ground output swing - making it suitable for low-voltage single-supply systems where headroom is constrained and precision DC coupling is required.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain Bandwidth Product	3.5 MHz - enables stable closed-loop operation up to ~350 kHz at gain = 10 without peaking.
Slew Rate	5.5 V/µs - supports fast step response in active filters and signal reconstruction circuits.
Input Offset Voltage	Max 10 mV (TS274I) - sets worst-case DC error in precision amplification stages.
Supply Current per Amp	1.6 mA max at T_A = 125°C - balances speed and power in thermally demanding environments.
Common-Mode Rejection	65–80 dB - suppresses noise from shared supply rails in multi-channel sensor systems.
Output Voltage Swing	0 V to V_CC − 1.5 V - allows full-range signal capture near ground in single-supply configurations.
Phase Margin	≥40° with 100 pF load - ensures stable operation driving ADC input capacitors or long PCB traces.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV914IDT	Rail-to-rail I/O, lower V_io (1.5 mV max), higher GBP (8 MHz), lower supply range (2.5–5.5 V).	Better suited for battery-powered, low-voltage (<5 V) systems requiring higher precision and bandwidth.	Select when operating below 5 V or needing sub-mV offset; not drop-in due to supply and output swing limits.
LM324DT	Bipolar input, higher I_ib (45 nA), lower GBP (1.2 MHz), no rail-to-ground output (V_OL ≈ 20 mV min).	Cost-optimized general-purpose use where ultra-low bias current and ground-swing are not required.	Choose for legacy designs or cost-sensitive applications where CMOS advantages are unnecessary.

Compared with TSV914IDT and LM324DT, TS274IDT uniquely balances industrial temperature rating, rail-to-ground output, ultra-low input bias, and 3.5 MHz bandwidth - making it optimal for robust, medium-speed analog signal conditioning in harsh environments where bipolar or modern RRIO op-amps fall short in voltage range or thermal specification.

FAQ

Is TS274IDT pin-compatible with other TS27x quad op-amps?

Yes - TS274IDT uses the standard 14-pin SO/TSSOP/DIP quad op-amp pinout defined across the TS27L4, TS27M4, and TS274 families. All share identical pin functions and package footprints, enabling direct substitution where supply current and offset specifications align with design requirements.

What is the maximum capacitive load TS274IDT can drive while maintaining stability?

TS274IDT is unity-gain stable with up to 100 pF capacitive load, as confirmed by phase margin ≥40° in Figure 10 of the datasheet. For loads exceeding 100 pF, external series resistance (typically 10–100 Ω) at the output is recommended to preserve stability without degrading bandwidth significantly.

Does TS274IDT support true single-supply operation from 3 V?

Yes - TS274IDT operates from 3 V to 16 V with guaranteed specifications, including rail-to-ground output swing and common-mode input range extending to 0 V. At 3 V supply, output swings from 0 V to ~1.5 V, and input common-mode range covers 0 V to 1.5 V, enabling functional single-supply use in low-voltage systems.

How does TS274IDT's input bias current compare to JFET-input op-amps?

TS274IDT's CMOS input delivers ≤300 pA max input bias current at 125°C - significantly lower than typical JFET op-amps (e.g., TL074: ~300 pA at 25°C, rising to >1 nA at 125°C). Its bias current also exhibits lower temperature drift, improving long-term DC accuracy in high-impedance sensor interfaces.
