STMicroelectronics TS932IDT

Overview

TS932IDT from STMicroelectronics is a dual rail-to-rail output micropower operational amplifier in SO-8 package, operating from 2.7 V to 10 V single supply, consuming only 20 μA per amplifier (typ), with 2 mV max input offset voltage (TS932B grade), 100 kHz gain-bandwidth product, and 50 V/ms slew rate. It serves as a precision signal conditioning front-end in low-power sensor interfaces and portable instrumentation.

For engineers reviewing the TS932IDT datasheet, TS932IDT pinout, TS932IDT application, or TS932IDT equivalent, key selection criteria include micropower operation under 3 V supply, rail-to-rail output swing down to 10 mV from rails, ultra-low 1 pA input bias current, CMOS input stage compatibility with high-impedance sources, and automotive-grade availability (TS932BIDT variant).

Technical Context

The TS932IDT implements a CMOS-input dual op-amp architecture optimized for single-supply battery operation, with rail-to-rail output stage enabling full dynamic range utilization at low voltages (e.g., 2.95 V high-level output at 3 V supply, RL = 100 kΩ). Its input common-mode range extends from VCC− −0.2 V to VCC+ −1.5 V, supporting ground-referenced sensing without level-shifting.

It features 85 dB typical CMRR and SVR across −40 °C to +105 °C, phase margin of 65° with 50 pF load, and 75 nV/√Hz input voltage noise - characteristics validated for stable closed-loop operation in high-precision DC-coupled amplifiers and pH meter front-ends where offset drift ≤3 μV/°C matters.

Key Specifications

Pinout & Package

TS932IDT is housed in an SO-8 (Small Outline-8) plastic package with 1.27 mm pitch, 4.9 mm × 6.0 mm body, and ECOPACK® RoHS-compliant finish. Pin 1 is marked by a notch or dot; top-view pin numbering follows standard SO-8 convention.

FAQ

What is the maximum operating temperature for TS932IDT?

The TS932IDT is rated for operation from −40 °C to +105 °C ambient temperature, meeting industrial and automotive-grade requirements. This range is validated per Table 3 in the official datasheet (Doc ID 6911 Rev 5), with electrical characteristics guaranteed across the full span including supply current, offset voltage, and CMRR performance.

Does TS932IDT support true rail-to-rail input?

No - TS932IDT features rail-to-rail *output* only. Its input common-mode voltage range is specified as VCC− −0.2 V to VCC+ −1.5 V, meaning the inputs cannot accept signals within 1.5 V of the positive rail. This limitation is intentional to maintain CMOS input stage stability and is documented in Table 3 of the datasheet.

Can TS932IDT drive a 10 kΩ load at 3 V supply?

Yes - TS932IDT can source and sink up to 1.5 mA (per amplifier) with VO within 10 mV of either rail at 3 V supply and RL = 100 kΩ. At RL = 10 kΩ, output swing degrades slightly (to ~2.85 V high / 0.15 V low), but remains functional for most ADC driver and comparator interface applications per Figure 11 and Figure 12 in the datasheet.

Is there a lead-free and RoHS-compliant version of TS932IDT?

Yes - TS932IDT is manufactured in ST's ECOPACK®-compliant SO-8 package, fully RoHS-compliant and halogen-free per ST's environmental policy. The "DT" suffix denotes tape-and-reel packaging with lead-free terminations, verified in Table 10 (Ordering Information) and Package Information section (page 10–14) of Doc ID 6911 Rev 5.
