Product details
Overview
TS512AIYDT from STMicroelectronics is a precision dual operational amplifier in SO-8 package, designed for high-stability voltage-follower and active-filter configurations. It delivers 3 MHz gain bandwidth, ≤500 µV input offset voltage (A-grade), ±1.5 to ±15 V dual-supply operation, and 120 dB channel separation - enabling telecom-grade signal conditioning in professional audio and instrumentation systems.
For engineers reviewing the TS512AIYDT datasheet, TS512AIYDT pinout, TS512AIYDT application, or TS512AIYDT equivalent, key selection criteria include guaranteed low Vio drift (2 µV/°C), automotive-grade qualification per AEC-Q100, stable unity-gain performance with capacitive loads up to 100 pF, and ESD robustness (2 kV HBM).
Technical Context
The TS512AIYDT integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external compensation - a critical advantage over uncompensated op-amps requiring external RC networks. Its macromodel-validated architecture supports accurate SPICE simulation of large-signal transient behavior under ±15 V supply conditions.
It operates across –40 °C to +125 °C with rail-to-rail output swing (±13 V into 2 kΩ at ±15 V), maintains 90 dB CMRR and SVRR over full common-mode range (VCC–+1.5 V to VCC++1.5 V), and exhibits <0.03% THD at 1 kHz - confirming suitability for low-distortion analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz, supporting anti-aliasing filter design up to 100 kHz. |
| Input Offset Voltage (max) | 500 µV - ensures ≤0.5 mV DC error in 10× gain sensor amplifiers without trimming. |
| Slew Rate | 0.8 V/µs - supports 2 Vpp output at 100 kHz without slew-induced distortion. |
| Channel Separation | 120 dB at 1 kHz - prevents crosstalk in dual-channel instrumentation such as stereo preamps or differential ADC drivers. |
| ESD Protection | 2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level handling in industrial assembly. |
| Supply Voltage Range | ±1.5 V to ±15 V - allows direct interface with ±5 V or ±12 V legacy systems without level-shifting. |
| Input Bias Current (max) | 300 nA - permits use with high-impedance sources (e.g., piezoelectric sensors) without significant DC error. |
Pinout & Package
TS512AIYDT is housed in an SO-8 (plastic micropackage) with standard 1.27 mm pitch, compliant with ECOPACK® environmental specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node for feedback network connection; referenced to V– during single-supply operation. |
| 2 | Non-inverting Input (Channel A) | Accepts DC-biased or AC-coupled signals; common-mode range extends to within 1.5 V of rails. |
| 3 | Output (Channel A) | Capable of sourcing/sinking 23 mA; drives 2 kΩ load to ±13 V with ±15 V supplies. |
| 4 | V– (Negative Supply) | Reference for dual-supply operation; tied to GND in single-supply mode (3–30 V). |
| 5 | V+ (Positive Supply) | Accepts up to +30 V (single) or ±15 V (dual); thermal shutdown activates above Tj = +150 °C. |
| 6 | Inverting Input (Channel B) | Independent of Channel A; enables dual-path filtering without inter-channel coupling. |
| 7 | Non-inverting Input (Channel B) | Matches Channel A specs; supports matched gain-setting resistor networks for differential pairs. |
| 8 | Output (Channel B) | Electrically isolated from Channel A output; 120 dB separation verified at 1 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Phase Compensation | Enables stable unity-gain follower operation without external components - reduces BOM count and layout sensitivity. |
| Automotive Qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C) - validated for engine control, ADAS sensor interfaces, and infotainment power stages. |
| Low Distortion & Noise | 0.03% THD at 1 kHz and 8 nV/√Hz input noise - preserves SNR in microphone preamplifiers and medical ECG front-ends. |
| Short-Circuit Protection | Current-limited outputs survive indefinite short to either rail - eliminates need for external current-limiting resistors. |
| Macromodel Included | Validated SPICE model (Table 4, Figure 22) enables accurate transient simulation of large-signal settling and stability margins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IDT | Lower Vio (1.5 mV typ), higher GBP (8 MHz), but no AEC-Q100 qualification. | Preferred for consumer audio where temperature range is limited to 0–70 °C. | Select when higher speed is required and automotive qualification is unnecessary. |
| LM2904VQDR | Higher Vio (3 mV max), lower GBP (1.2 MHz), but wider supply range (up to 36 V). | Used in 24 V industrial controls where extended voltage tolerance outweighs precision needs. | Select for cost-sensitive 24 V systems where 500 µV Vio is not mandatory. |
Compared with TS512AIYDT, TSV912IDT trades automotive reliability for bandwidth, while LM2904VQDR sacrifices precision and speed for broader supply flexibility - making TS512AIYDT optimal for temperature-stable, low-distortion dual-channel designs in automotive and telecom infrastructure.

FAQ
Is TS512AIYDT pin-compatible with TS512IDT?
Yes - both share identical SO-8 pinout and electrical specifications except for input offset voltage grading: TS512AIYDT guarantees ≤500 µV max Vio (A-grade), while TS512IDT specifies ≤1.5 mV max. Thermal and supply ratings are identical, allowing drop-in replacement where tighter Vio is required.
Can TS512AIYDT operate from a single 5 V supply?
Yes - its specified single-supply range is 3 V to 30 V. At 5 V, it delivers ±3 V output swing into 2 kΩ (per Table 3), with common-mode input range from 1.5 V to 3.5 V. Input bias current remains below 300 nA, supporting high-impedance sensor interfaces.
What is the maximum capacitive load TS512AIYDT can drive stably?
Per Figure 13–15 in the datasheet, TS512AIYDT maintains ≥55° phase margin with up to 100 pF capacitive load at VCC = ±15 V. For loads >100 pF, external isolation resistance (≥100 Ω) is recommended to prevent peaking or oscillation in unity-gain configurations.
Does TS512AIYDT include ESD protection on all pins?
Yes - it features 2 kV HBM ESD protection on all input and output pins, verified per JEDEC JS-001. This includes both inverting/non-inverting inputs and outputs, enabling robust handling during PCB assembly and field service without additional TVS diodes.
