Product details
Overview
TS512IDT 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 product, 0.5 mV max input offset voltage (TS512A/B variants), ±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 TS512IDT datasheet, TS512IDT pinout, TS512IDT application, or TS512IDT equivalent, key selection criteria include input offset voltage drift (2 µV/°C), slew rate (0.8 V/µs), common-mode rejection (90 dB), and guaranteed operation from –40 °C to +125 °C in industrial environments.
Technical Context
The TS512IDT integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external components despite its 3 MHz GBP. Its macromodel-validated architecture supports accurate SPICE simulation of closed-loop behavior across capacitive loads up to 100 pF.
It features rail-to-rail output swing (±13 V at ±15 V supplies), low distortion (0.03% THD), and ESD protection rated at 2 kV HBM - all while maintaining <0.75 mA per-channel supply current over its full ±1.5 to ±15 V dual-supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - enables stable active filtering up to ~200 kHz with 10× gain margin |
| Input Offset Voltage (max) | 0.5 mV - ensures ≤500 µV DC error in precision sensor front-ends at 25 °C |
| Slew Rate | 0.8 V/µs - supports 100 kHz full-power sine wave output at 10 Vpp into 2 kΩ |
| Channel Separation | 120 dB at 1 kHz - prevents crosstalk in dual-channel instrumentation amplifiers |
| Common-Mode Rejection | 90 dB - rejects >30 kΩ imbalance-induced errors in differential sensing |
| Supply Voltage Range | ±1.5 to ±15 V - operates from single 3–30 V or dual ±1.5–±15 V rails |
| Operating Temperature | –40 to +125 °C - qualified for industrial control and telecom infrastructure |
Pinout & Package
TS512IDT is housed in an SO-8 (plastic micropackage) with standard 1.27 mm pitch, 5.0 mm × 6.2 mm body, and ECOPACK® RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node for feedback network connection in op-amp configurations |
| 2 | Non-inverting Input (Channel A) | Reference input for differential gain stages; CMVR extends to VCC– +1.5 V |
| 3 | Output (Channel A) | Capable of ±13 V swing into 2 kΩ load; short-circuit protected |
| 4 | VCC+ | Positive supply terminal; accepts up to +15 V in dual-rail or +30 V in single-rail mode |
| 5 | VCC– | Negative supply terminal; supports –15 V or ground reference in single-supply use |
| 6 | Inverting Input (Channel B) | Independent input for second amplifier; electrically isolated from Channel A |
| 7 | Non-inverting Input (Channel B) | Matches Channel A specs; enables matched dual-path signal processing |
| 8 | Output (Channel B) | Identical performance to Pin 3; 120 dB isolation minimizes inter-channel coupling |
Key Features
| Feature | Design Value |
|---|---|
| Low input offset voltage | 0.5 mV max (TS512A/B) - reduces DC calibration burden in 16-bit data acquisition |
| Internal phase compensation | Stable unity-gain follower operation - eliminates need for external compensation networks |
| High channel separation | 120 dB at 1 kHz - preserves signal integrity in stereo audio preamps and dual ADC drivers |
| ESD protection | 2 kV HBM - withstands handling in uncontrolled assembly environments without additional protection |
| Wide supply range | Single 3–30 V or dual ±1.5–±15 V - simplifies power architecture in mixed-voltage systems |
Applications
| Active Low-Pass Filter | Instrumentation Amplifier Front-End |
|---|---|
|
Use Scenario: 2nd-order Sallen-Key filter for anti-aliasing before 100 kSPS SAR ADC in industrial PLC analog input modules. IC Role / Device Role / Timing Role: Dual op-amp implements buffered input stage and unity-gain integrator; one channel conditions sensor signal, the other provides reference buffering. Use Value: 3 MHz GBP and 120 dB channel separation prevent passband ripple and inter-channel feedthrough below 50 kHz cutoff. |
Use Scenario: Precision bridge amplifier for strain-gauge-based load cells in factory-floor weighing systems. IC Role / Device Role / Timing Role: First-stage differential amplifier (Channel A) and reference buffer (Channel B) - both operating within same IC die for matched thermal drift. Use Value: 2 µV/°C offset drift and 0.5 mV max Vio ensure ≤0.1% full-scale error over –25 to +85 °C ambient range. |
| Telecom Line Driver | Professional Audio Mixer Channel |
|
Use Scenario: Balanced line driver for T1/E1 interface cards requiring 0–2.048 MHz flat response and low harmonic distortion. IC Role / Device Role / Timing Role: Dual-channel configured as inverting gain stage (Channel A) and non-inverting gain stage (Channel B) for differential output generation. Use Value: 0.03% THD at 1 kHz and 90 dB CMRR maintain signal fidelity across long PCB traces and connector interfaces. |
Use Scenario: Dual-path microphone preamplifier with variable gain and phantom power conditioning in broadcast mixing consoles. IC Role / Device Role / Timing Role: One channel amplifies XLR input (inverting), the other buffers +48 V phantom supply (non-inverting follower). Use Value: Short-circuit protection and ±15 V supply tolerance allow safe operation during live patching and hot-swapping of inputs. |
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 (3 mV max), lower GBP (3 MHz typ but not guaranteed min), no 125 °C rating | Limited to commercial-temp applications; unsuitable for industrial control cabinets | Select only if cost-sensitive and operating ≤85 °C with relaxed offset requirements |
| OPA2188AIDR | Zero-drift architecture, 0.003 µV/°C drift, 2 MHz GBP, higher quiescent current (1 mA/ch) | Better for ultra-low-drift DC-coupled systems but less suitable for wideband AC signals | Prefer when sub-µV offset stability over temperature is critical, not raw bandwidth |
Compared with TL072CDR and OPA2188AIDR, TS512IDT uniquely balances industrial temperature range, guaranteed 0.5 mV Vio, 3 MHz GBP, and 120 dB channel separation - making it optimal for dual-path signal chains where thermal tracking and AC performance are equally essential.

FAQ
Is TS512IDT pin-compatible with TS512AIDT and TS512BIYDT?
Yes - all TS512x variants share identical SO-8 pinout and footprint. TS512IDT (industrial grade, –40 to +125 °C) and TS512AIDT differ only in input offset voltage specification (0.5 mV vs. 2.5 mV max), while TS512BIYDT adds automotive qualification (AEC-Q100) and higher slew rate (1.072 V/µs). No layout change is required for substitution within same temperature grade.
Can TS512IDT operate from a single 5 V supply?
Yes - TS512IDT supports single-supply operation from 3 V to 30 V. At 5 V, its common-mode input range is 1.5 V to 3.5 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 TS512IDT include SPICE macromodel support?
Yes - ST provides a validated PSpice macromodel in the official datasheet (DocID004948 Rev 8, Section 4.2). The model replicates key behaviors including GBP, slew rate, input bias current, and channel separation, and is intended for pre-layout AC/DC and transient analysis under nominal ±15 V conditions.
What is the thermal resistance (RthJA) of TS512IDT in SO-8 package?
The datasheet specifies RthJA = 125 °C/W for the SO-8 package under standard JEDEC JESD51-2 test conditions (single-layer board, 1 in² copper pad). Actual junction temperature rise depends on PCB copper area, airflow, and power dissipation - maximum allowed dissipation at +125 °C ambient is ~400 mW per channel.
