Product details
Overview
TS912BIYDT from STMicroelectronics is a rail-to-rail input/output CMOS dual operational amplifier designed for precision analog signal conditioning in single- or dual-supply systems. It operates from 2.7 V to 16 V, delivers 2 mV max input offset voltage (TS912B grade), draws only 200 μA per amplifier at 3 V, and supports 600 Ω load drive - enabling use in battery-powered sensor front-ends and automotive body control modules.
For engineers reviewing the TS912BIYDT datasheet, TS912BIYDT pinout, TS912BIYDT application, or TS912BIYDT equivalent, key selection criteria include rail-to-rail I/O swing under low supply (2.7 V), sub-1 pA input bias current at 25 °C, guaranteed 125 °C operation, and AEC-Q100 qualified SO-8 packaging for automotive-grade reliability.
Technical Context
The TS912BIYDT implements a complementary CMOS input stage enabling rail-to-rail common-mode input range (VCC− − 0.2 V to VCC+ + 0.2 V) and output swing within 30 mV of VCC− and 40 mV of VCC+ (RL = 10 kΩ). Its internal current-limiting circuit fixes source/sink capability at 40 mA per amplifier at 3 V, while phase margin remains stable at ≥30° across 3–16 V supply and 10 kΩ/600 Ω loads.
It features matched dual amplifiers with 120 dB channel separation at 1 kHz, 30 nV/√Hz input noise, and gain-bandwidth product scaling from 0.8 MHz (3 V) to 1.4 MHz (10 V), supporting stable unity-gain and closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables direct interface with Li-ion, 5 V, and 12 V automotive rails without level-shifting. |
| Input Offset Voltage (max) | 2 mV (TS912B grade, −40 °C to +125 °C) - ensures ≤20 mV error in 10× gain sensor amplification at full temperature range. |
| Input Bias Current (typ) | 1 pA at 25 °C - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback). |
| Supply Current per Amplifier | 200 μA at 3 V - allows dual-channel operation below 500 μW total quiescent power in always-on monitoring circuits. |
| Output Drive Capability | 40 mA sink/source (VCC = 3 V) - drives 600 Ω loads to rail with <400 mV headroom, supporting active filters and DAC buffers. |
| Gain-Bandwidth Product | 1.4 MHz at 10 V supply - supports stable 100 kHz signal bandwidth in G = 10 configurations with 10 kΩ load. |
| Common-Mode Rejection | 90 dB (min, VCC = 10 V) - rejects power-supply ripple and ground noise in single-supply instrumentation topologies. |
Pinout & Package
TS912BIYDT is supplied in an automotive-grade SO-8 package (ECOPACK®, RoHS-compliant, 4.9 mm × 6.0 mm × 1.75 mm height), qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance node accepting differential signal; rail-to-rail common-mode range supports direct connection to sensors near supply rails. |
| 2 | Non-inverting Input (Amplifier A) | CMOS input with 1 pA bias current; requires guarded layout to preserve low-noise performance in high-Z applications. |
| 3 | Output (Amplifier A) | Rail-to-rail output capable of sourcing/sinking 40 mA; specified down to 30 mV above VCC− and 40 mV below VCC+ with 10 kΩ load. |
| 4 | Positive Supply (VCC+) | Accepts 2.7–16 V; decoupling capacitor required within 1 cm to maintain PSRR >50 dB and stability under dynamic load. |
| 5 | Negative Supply (VCC−) | Ground reference for single-supply operation or negative rail in dual-supply; must be low-impedance to support 40 mA output swing. |
| 6 | Inverting Input (Amplifier B) | Electrically identical to Pin 1; independent channel enables dual-sensor conditioning or composite filter stages. |
| 7 | Non-inverting Input (Amplifier B) | Matches Pin 2 characteristics; channel separation >120 dB prevents crosstalk in multi-channel signal chains. |
| 8 | Output (Amplifier B) | Functionally identical to Pin 3; dual outputs allow simultaneous processing of complementary signals (e.g., differential ADC drivers). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3 V systems: Vicm spans VCC− −0.2 V to VCC+ +0.2 V; VOH/VOL within 30–40 mV of rails (10 kΩ load). |
| Ultra-low input bias current | 1 pA typical at 25 °C - preserves accuracy in high-source-impedance circuits (e.g., piezoelectric sensors, electrochemical cells) without guard traces. |
| AEC-Q100 qualified SO-8 | Automotive-grade qualification (Grade 1, −40 °C to +125 °C) with traceable lot control - suitable for body electronics, HVAC controls, and lighting modules. |
| Specified for 600 Ω loads | Guaranteed output swing and linearity into low-impedance loads - supports driving ADC reference buffers, active RC filters, and LED current sinks directly. |
| Latch-up immunity & ESD robustness | Immune to latch-up per JEDEC JESD78; 3 kV HBM ESD rating - reduces system-level protection component count in exposed I/O designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail CMOS op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS912IDT | Industrial grade (−40 °C to +125 °C), same SO-8 package, but not AEC-Q100 qualified; 12 mV max Vio (TS912 grade). | Lower accuracy and no automotive qualification - suitable for cost-sensitive industrial controls where extended temp range suffices. | Select when AEC-Q100 is unnecessary and Vio ≤12 mV meets system error budget. |
| MCP6022-E/SN | Microchip device; 3.5 mV max Vio, 100 pA Iib (typ), 1 MHz GBP, SO-8; lacks 600 Ω load specification and AEC-Q100 certification. | Higher input bias current degrades high-Z sensor accuracy; no guaranteed 600 Ω drive limits use in low-impedance active filters. | Choose only for non-automotive, lower-precision applications where 100 pA Iib is acceptable and 600 Ω loading is unused. |
Compared with TS912IDT, TS912BIYDT provides tighter offset (2 mV vs. 12 mV) and automotive qualification; versus MCP6022-E/SN, it offers superior input bias current (1 pA vs. 100 pA) and verified 600 Ω load drive - critical for sensor signal integrity in harsh environments.

FAQ
What is the maximum operating junction temperature for TS912BIYDT?
The absolute maximum junction temperature is 150 °C, with continuous operation rated up to 125 °C ambient per AEC-Q100 Grade 1. Thermal resistance junction-to-ambient is 125 °C/W (SO-8), so at 200 μA per amplifier and 5 V supply, power dissipation remains below 2 mW per channel - well within safe thermal margins even in sealed enclosures.
Does TS912BIYDT require external compensation for unity-gain stability?
No external compensation is required: the TS912BIYDT is internally compensated for unity-gain stability across its full supply range (2.7–16 V) and load conditions (100 Ω to 10 kΩ). Phase margin exceeds 30° at 3 V and 40° at 10 V with 10 kΩ load, as verified in Figures 10 and 13 of the datasheet.
Can TS912BIYDT drive capacitive loads directly?
Capacitive loads >100 pF require series output resistance (≥100 Ω) to maintain stability, as indicated by reduced phase margin in Figure 11 (RL = 600 Ω) and Figure 13. The datasheet specifies CL = 100 pF in GBP and slew rate tests - larger capacitive loads risk ringing or oscillation without isolation.
How does the TS912B grade differ from TS912 and TS912A in production screening?
TS912B guarantees ≤2 mV input offset voltage across −40 °C to +125 °C, tighter than TS912A (≤3 mV) and TS912 (≤12 mV); all grades share identical pinout, package, and electrical architecture. Screening includes extended temperature testing and statistical binning - no functional or reliability differences beyond Vio specification.
