STMicroelectronics TS912ID

Overview

TS912ID from STMicroelectronics is a rail-to-rail input/output CMOS dual operational amplifier operating from 2.7 V to 16 V single supply (or ±13.5 V dual supply), delivering 200 μA/amplifier quiescent current at 3 V, 2 mV max input offset voltage (TS912B grade), and rail-to-rail output swing within 40 mV of rails into 10 kΩ. It serves precision sensor signal conditioning in industrial temperature transmitters.

For engineers reviewing the TS912ID datasheet, TS912ID pinout, TS912ID application, or TS912ID equivalent, key selection criteria include rail-to-rail input common-mode range (VCC−–0.2 V to VCC++0.2 V), low 1 pA typical input bias current, latch-up immunity, 3 kV HBM ESD rating, and SO-8 package compatibility with space-constrained analog front-ends.

Technical Context

The TS912ID implements a CMOS input stage enabling rail-to-rail common-mode operation down to VCC− and up to VCC+, with input bias current stable across −40 °C to +125 °C. Its output stage uses internal current limiting to deliver ±40 mA sink/source capability at 3 V while maintaining rail-to-rail swing-30 mV above VCC− and 40 mV below VCC+ into 10 kΩ.

Gain-bandwidth product scales with supply voltage (0.8 MHz at 3 V, 1.4 MHz at 10 V) and load (1 MHz at 10 kΩ, reduced under 600 Ω). Phase margin remains ≥30° across 2.7–16 V supply and 100 Ω–100 kΩ loads, ensuring stability in unity-gain buffer and active filter configurations without external compensation.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, analog ICs, power management, and MEMS sensors for industrial, automotive, and consumer markets.

The TS912 series belongs to ST's precision analog portfolio, engineered specifically for rail-to-rail performance in low-power industrial sensing and signal conditioning applications where input bias current and offset voltage directly impact measurement fidelity.

FAQ

What is the maximum capacitive load the TS912ID can drive without instability?

The TS912ID is characterized for stable operation with up to 100 pF capacitive load when driving 10 kΩ resistive loads, as verified in Figure 8 (gain/phase vs. frequency). Driving >100 pF requires isolation resistor (≥100 Ω) between output and capacitance to maintain ≥30° phase margin per Figure 11 and 13 data.

Does TS912ID support dual-supply operation, and what are the limits?

Yes, TS912ID supports dual-supply operation with VCC+ up to +16 V and VCC− down to −16 V (absolute max ±18 V), enabling ±13.5 V operation. Common-mode input range extends 0.2 V beyond each rail, and output swing reaches within 40 mV of either supply under 10 kΩ load, making it suitable for bipolar signal processing.

How does the 1 pA input bias current behave over temperature?

Per Figure 5, input bias current remains ≤150 pA across −40 °C to +125 °C for the TS912B grade. At 25 °C, it is typically 1 pA; at 125 °C, it rises to ~100 pA-still 10× lower than bipolar-input op-amps, preserving accuracy in high-impedance sensor circuits over full industrial range.

Is the SO-8 package of TS912ID RoHS and REACH compliant?

Yes, TS912ID is manufactured in ST's ECOPACK®-compliant SO-8 package, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead finish is matte tin, and halogen-free molding compound is used-fully documented in ST's ECOPACK® database at www.st.com.
