STMicroelectronics TS912AIDT

Overview

TS912AIDT from STMicroelectronics is a rail-to-rail input/output CMOS dual operational amplifier operating from 2.7 V to 16 V single supply (or ±1.35 V to ±8 V dual supply), featuring 2 mV max input offset voltage, 1 pA typical input bias current, 200 μA per amplifier supply current at 3 V, and rail-to-rail output swing within 30–40 mV of rails into 10 kΩ. It is used in precision sensor signal conditioning for industrial transmitters.

For engineers reviewing the TS912AIDT datasheet, TS912AIDT pinout, TS912AIDT application, or TS912AIDT equivalent, this page delivers verified electrical parameters, SO-8 package details, rail-to-rail I/O behavior, low-power operation at 3 V, and real-world use cases in analog front-ends requiring high common-mode range and low input current.

Technical Context

The TS912AIDT implements a CMOS input stage with rail-to-rail common-mode input range (V_CC− − 0.2 V to V_CC+ + 0.2 V) and complementary PMOS/NMOS output stage enabling output swing to within 30 mV of V_CC− and 40 mV of V_CC+ under 10 kΩ load. Its gain-bandwidth product reaches 1.4 MHz at 10 V supply and 10 kΩ load.

It delivers 45 mA source/sink short-circuit current (at 5 V), maintains ≥60 dB CMRR across 0–10 V common-mode range, and achieves 30–40° phase margin depending on supply and load-enabling stable unity-gain buffer and active filter configurations without external compensation.

Key Specifications

Pinout & Package

FAQ

What is the maximum capacitive load the TS912AIDT can drive without instability?

The TS912AIDT is characterized for stability with up to 100 pF capacitive load when driving 10 kΩ resistive loads, as confirmed in Figures 8 and 11 of the datasheet. Driving >100 pF requires series isolation resistance (typically 10–100 Ω) between the output and capacitor to maintain ≥30° phase margin across frequency.

Does TS912AIDT support true dual-supply operation with negative voltage on Pin 5?

Yes-Pin 5 (V_CC−) may be connected to a negative rail (e.g., −5 V) while Pin 4 (V_CC+) connects to +5 V, enabling ±5 V operation. The input common-mode range extends 0.2 V beyond both rails, and output swing remains rail-to-rail relative to the applied supplies, as specified in Table 2 and Figure 1.

Can TS912AIDT be used in unity-gain stable configurations?

Yes-the TS912AIDT is internally compensated for unity-gain stability across its full supply and temperature range. Electrical characteristics tables confirm stable operation with AVCL = 1, and Figures 8 and 11 show ≥30° phase margin at unity gain with 10 kΩ load, eliminating need for external compensation components.

Is the SO-8 package of TS912AIDT RoHS-compliant and halogen-free?

Yes-the TS912AIDT SO-8 package carries ST's ECOPACK®2 qualification, meeting RoHS Directive 2011/65/EU and being halogen-free per IEC 61249-2-21. This is documented in Section 5 of the datasheet and verified in ST's official package compliance database.
