Product details
Overview
TS512AID 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 max input offset voltage (A version), ±1.5 to ±15 V dual supply operation, and 120 dB channel separation - enabling accurate signal conditioning in telecom and professional audio front-ends.
For engineers reviewing the TS512AID datasheet, TS512AID pinout, TS512AID application, or TS512AID equivalent, key selection criteria include input offset voltage drift (2 µV/°C), slew rate (0.8 V/µs), common-mode rejection (90 dB), supply voltage rejection (90 dB), and thermal stability across –40 °C to +125 °C operating range.
Technical Context
The TS512AID integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external compensation components. Its macromodel-validated architecture supports robust performance across wide supply ranges (±1.5 V to ±15 V) and maintains consistent gain-bandwidth (3 MHz typ.) and CMR (90 dB) over temperature.
It features rail-to-rail output swing capability (±13 V at ±15 V supplies), low distortion (0.03% THD), and ESD protection rated at 2 kV HBM - making it suitable for precision analog signal paths where channel crosstalk and DC accuracy are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ≤500 µV max (A-grade spec); ensures ≤0.5 mV total error in DC-coupled sensor interfaces |
| Gain bandwidth product | 3 MHz typ.; supports stable closed-loop operation up to ~200 kHz with gain ≥15 |
| Slew rate | 0.8 V/µs min; enables clean 100 kHz sine output at 2 Vpp without slewing distortion |
| Common-mode rejection | 90 dB min; rejects >30 kΩ imbalance-induced interference in differential input stages |
| Supply voltage range | ±1.5 V to ±15 V dual; accommodates legacy ±5 V, ±12 V, and modern ±15 V industrial rails |
| Channel separation | 120 dB at 1 kHz; prevents crosstalk in dual-channel instrumentation amplifiers or stereo filters |
| Input bias current | 300 nA max; allows use with high-impedance sources (e.g., piezoelectric sensors, photodiode TIA feedback) |
Pinout & Package
TS512AID is housed in an SO-8 (plastic micropackage) with standard 1.27 mm pitch, 5.0 mm × 6.2 mm body, and 1.75 mm height per ECOPACK® specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel A) | High-impedance node for feedback network connection; referenced to internal differential pair |
| 2 | Non-inverting input (Channel A) | DC-coupled input path with ±13.4 V to +14 V common-mode range at ±15 V supply |
| 3 | Output (Channel A) | Capable of ±13 V swing into 2 kΩ load; short-circuit protected to 23 mA |
| 4 | Positive supply (VCC+) | Accepts up to +15 V; internal biasing derived directly from this rail |
| 5 | Negative supply (VCC–) | Accepts down to –15 V; defines lower common-mode and output swing limit |
| 6 | Inverting input (Channel B) | Independent high-Z input; electrically isolated from Channel A except via substrate coupling |
| 7 | Non-inverting input (Channel B) | Matches Pin 2 specs; enables dual-channel matched filtering or parallel gain stages |
| 8 | Output (Channel B) | Identical drive capability to Pin 3; 120 dB isolation minimizes inter-channel signal leakage |
Key Features
| Feature | Design Value |
|---|---|
| Low input offset voltage | 500 µV max (A version) enables sub-mV DC error in 12-bit data acquisition front-ends |
| Internal phase compensation | Stable unity-gain follower operation without external capacitor; reduces PCB area and BOM count |
| Wide supply range | Operates from ±1.5 V to ±15 V - supports both low-voltage portable and high-dynamic-range industrial rails |
| High channel separation | 120 dB at 1 kHz ensures <1 µV coupling between channels in dual active filter banks |
| ESD protection | 2 kV HBM rating protects against handling damage during assembly and field service |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP2177ARZ | Lower Vio (25 µV max), higher GBP (1.3 MHz), but only ±15 V max supply; no ESD rating specified | Better for ultra-low-offset DC-critical apps (e.g., strain gauge bridges); less suitable for wide-supply telecom systems | Select when Vio < 100 µV is mandatory and supply is fixed at ±15 V |
| LM2904DT | Higher Vio (7 mV max), lower GBP (1.2 MHz), wider temp range (–40 °C to +125 °C), lower cost | Acceptable for cost-sensitive consumer audio or basic sensor amps where 12-bit accuracy suffices | Select when budget constraints outweigh precision requirements and 12-bit ENOB is sufficient |
Compared with OP2177ARZ and LM2904DT, TS512AID uniquely balances 500 µV Vio, 3 MHz GBP, ±15 V operation, and 2 kV ESD protection - making it optimal for telecom and industrial analog signal chains demanding both precision and ruggedness.

FAQ
What is the maximum operating junction temperature for TS512AID?
The absolute maximum junction temperature is +150 °C, with continuous operation supported from –40 °C to +125 °C ambient. Thermal resistance junction-to-ambient is 125 °C/W in SO-8 package, requiring ≤300 mW total dissipation for safe operation at full temperature range.
Does TS512AID support single-supply operation?
Yes - TS512AID operates from 3 V to 30 V single supply, with common-mode input range extending from VCC– +1.5 V to VCC+ –1.5 V. Output swing reaches within 2 V of each rail under 2 kΩ load, enabling use in 5 V or 24 V unipolar systems.
Is the TS512AID pin-compatible with other TS512x variants?
Yes - TS512, TS512A, and TS512B share identical SO-8 pinout, electrical interface, and package dimensions. Only performance parameters differ: TS512A guarantees ≤500 µV Vio, while TS512B adds 1.072 V/µs slew rate versus 0.8 V/µs for TS512/TS512A.
Where can I find the SPICE macromodel for TS512AID?
A validated SPICE macromodel is included in the official datasheet (DocID004948 Rev 8, Section 4.2), supporting simulation of open-loop gain, phase margin, and transient response.
