Product details
Overview
TS512ID 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, 0.8 V/µs slew rate (TS512/TS512A), and low input offset voltage (≤1.5 mV max) across –40 °C to +125 °C, supporting telecom-grade signal conditioning in ±15 V or 3–30 V single-supply systems.
For engineers reviewing the TS512ID datasheet, TS512ID pinout, TS512ID application, or TS512ID equivalent, key selection criteria include guaranteed channel separation (120 dB), ESD protection (2 kV HBM), wide common-mode input range (VCC–+1.5 V to VCC+–1.5 V), and macromodel availability for SPICE simulation of active filter stability.
Technical Context
The TS512ID integrates internal frequency and phase compensation, enabling stable unity-gain operation without external compensation-critical for precision follower topologies. Its bipolar input stage ensures low noise (8 nV/√Hz at 1 kHz) and low distortion (0.03% THD), while the high CMRR (90 dB) and PSRR (90 dB) maintain accuracy under supply and common-mode variation.
Designed for professional analog signal chains, it operates over full industrial temperature range (–40 °C to +125 °C) with rail-to-rail output swing capability (±13 V into 2 kΩ at ±15 V supplies) and short-circuit protection. Input bias current (50–300 nA) and offset drift (2 µV/°C) are specified across temperature, supporting DC-coupled instrumentation designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 3 MHz - enables stable active filters up to ~300 kHz with 10× gain margin |
| Slew rate | 0.8 V/µs - supports ≤80 kHz full-power sine output at 10 Vpp into 2 kΩ load |
| Input offset voltage | ≤1.5 mV (max) - limits DC error to <±15 mV in 10× inverting amplifier at room temp |
| Channel separation | 120 dB at 1 kHz - prevents crosstalk-induced intermodulation in dual-channel audio or sensor front-ends |
| Supply voltage range | ±1.5 V to ±15 V dual / 3 V to 30 V single - interoperable with legacy 5 V, modern 3.3 V, and high-voltage industrial rails |
| ESD protection | 2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level handling robustness |
| Common-mode input range | VCC–+1.5 V to VCC+–1.5 V - accommodates inputs within 1.5 V of either rail, easing level-shifting in mixed-supply systems |
Pinout & Package
TS512ID is housed in an SO-8 (plastic micropackage) with standard 1.27 mm pitch, ECOPACK®-compliant, and rated for 125 °C maximum operating junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel A) | High-impedance node for feedback network connection; matched to Pin 5 for common-mode rejection |
| 2 | Non-inverting input (Channel A) | DC-coupled input path; common-mode range extends to within 1.5 V of supply rails |
| 3 | Output (Channel A) | Capable of ±13 V swing into 2 kΩ at ±15 V supplies; short-circuit protected |
| 4 | Positive supply (VCC+) | Accepts 3–30 V single or +1.5 to +15 V dual; decoupling required within 1 cm for stability |
| 5 | Inverting input (Channel B) | Electrically isolated from Channel A; enables independent dual-path signal processing |
| 6 | Non-inverting input (Channel B) | Matched offset and bias characteristics to Pin 2; supports synchronous dual-channel design |
| 7 | Output (Channel B) | Identical AC/DC performance to Pin 3; 120 dB channel separation minimizes inter-channel coupling |
| 8 | Negative supply (VCC–) | Accepts 0 V (single supply) or –1.5 to –15 V (dual); referenced for all internal biasing |
Key Features
| Feature | Design Value |
|---|---|
| Internal phase compensation | Enables stable unity-gain voltage follower operation without external components, reducing BOM count and layout sensitivity |
| Low input offset voltage drift | 2 µV/°C - maintains ≤20 µV total offset shift over full –40 °C to +125 °C range, critical for uncalibrated sensors |
| High large-signal voltage gain | 90–100 dB - ensures ≤0.03% gain error in closed-loop configurations with ≥100× attenuation |
| Macromodel included | SPICE-compatible behavioral model provided for accurate transient and AC simulation of active filter roll-off and phase margin |
| Wide supply range operation | Supports direct interface with 3.3 V microcontrollers (single 3 V supply) and ±15 V legacy test equipment without level-shifting |
Applications

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 |
|---|---|---|---|
| TL072CDR | Higher Vio (6 mV max), lower GBP (3 MHz typ but not guaranteed), no 2 kV HBM rating | Limited to commercial-temp (0–70 °C) and non-automotive industrial use | Lower cost where extended temperature and ESD robustness are not required |
| OPA2188AIDR | Zero-drift architecture, 0.003 µV/°C drift, but higher supply current (1 mA/ch) and narrower supply range (±2.25 to ±18 V) | Better for ultra-low-drift DC applications; less suitable for high-output-swing AC signal paths | Preferred when sub-µV/°C drift dominates over power and voltage-range constraints |
Compared with TL072CDR, TS512ID offers superior temperature stability and ESD ruggedness; compared with OPA2188AIDR, it trades zero-drift performance for lower quiescent current and wider supply flexibility-making it optimal for cost-sensitive, wide-voltage, industrial-grade analog front-ends.

FAQ
Is TS512ID pin-compatible with TS512AIDT and TS512BIYDT?
Yes-TS512ID, TS512AIDT, and TS512BIYDT share identical SO-8 pinout and footprint. Differences lie in electrical grading: TS512ID specifies 1.5 mV max Vio, TS512AIDT tightens this to 0.5 mV max, and TS512BIYDT adds automotive qualification (AEC-Q100) plus higher slew rate (1.072 V/µs). All three are mechanically interchangeable.
Can TS512ID operate from a single 5 V supply?
Yes-TS512ID supports single-supply operation from 3 V to 30 V. At 5 V, its common-mode input range is 2.5 V to 3.5 V (VCC–+1.5 V to VCC+–1.5 V), and output swing reaches ≥3.5 Vpp into 10 kΩ. For rail-to-rail input/output, external level-shifting or a different op-amp family is required.
Does TS512ID require external compensation for unity-gain stability?
No-TS512ID features internal frequency and phase compensation optimized for stable unity-gain voltage-follower operation across its full supply and temperature range. The datasheet confirms stable step response and ≥55° phase margin at CL = 100 pF, eliminating need for external compensation networks in standard configurations.
What is the thermal resistance (RthJA) of TS512ID in SO-8 package?
The SO-8 package has a typical junction-to-ambient thermal resistance (RthJA) of 125 °C/W under standard JEDEC PCB conditions (2s2p copper). This value assumes minimal copper area; actual thermal performance improves with added thermal vias and copper pour connected to Pins 4 and 8 (power rails), enabling continuous operation at full ambient temperature (125 °C) with ≤300 mW total dissipation.
