Product details
Overview
TS512IYDT from STMicroelectronics is an automotive-grade precision dual operational amplifier in SO-8 package, featuring 3 MHz gain bandwidth product, 0.5 mV max input offset voltage (A-version), and ±1.5 to ±15 V dual supply operation. It delivers high channel separation (120 dB), low distortion (0.03% THD), and ESD protection (2 kV HBM), optimized for active filtering in telecom and professional audio signal conditioning.
For engineers reviewing the TS512IYDT datasheet, TS512IYDT pinout, TS512IYDT application, or TS512IYDT equivalent, key selection criteria include input offset voltage drift (2 µV/°C), slew rate (0.8 V/µs), common-mode rejection ratio (90 dB), and AEC-Q100 qualified automotive reliability - all critical for high-fidelity analog front-ends and sensor interface circuits.
Technical Context
The TS512IYDT integrates internal frequency and phase compensation, enabling stable unity-gain voltage follower operation despite its 3 MHz GBP. Its macromodel-validated architecture ensures predictable settling behavior under capacitive loads up to 100 pF across supply voltages from ±4 V to ±15 V.
It operates over –40 °C to +125 °C with rail-to-rail output swing (±13 V at ±15 V supplies) and maintains consistent input bias current (50–300 nA) and CMRR (90 dB) across the full common-mode range (VCC–+1.5 V to VCC+–1.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 3 MHz - supports stable closed-loop operation up to 100 kHz with gain ≥30 in active filter designs. |
| Input offset voltage (max) | 0.5 mV - enables sub-10 µV error in precision DC-coupled instrumentation amplifiers. |
| Slew rate | 0.8 V/µs - sufficient for 20 kHz full-power sine wave output at 10 Vpp without distortion. |
| Common-mode rejection ratio | 90 dB - rejects >30 kΩ of common-mode interference in differential sensor interfaces. |
| Supply voltage range | ±1.5 V to ±15 V - compatible with legacy ±5 V, ±12 V, and modern ±3.3 V systems via level-shifting. |
| Channel separation | 120 dB at 1 kHz - prevents crosstalk between dual-channel audio paths or multi-sensor signal chains. |
| ESD protection | 2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level robustness in automotive harness environments. |
Pinout & Package
TS512IYDT is housed in a standard SO-8 (plastic micropackage) with exposed pad not electrically connected. The package complies with ECOPACK® environmental specifications and supports reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel A) | High-impedance node for feedback network connection in inverting amplifier configurations. |
| 2 | Non-inverting input (Channel A) | Reference point for single-ended or differential input signals; tied to bias voltage in active filters. |
| 3 | Output (Channel A) | Capable of sourcing/sinking 23 mA; drives 2 kΩ loads to ±13 V swing at ±15 V supplies. |
| 4 | Positive supply (VCC+) | Accepts up to +15 V; decoupling capacitor required within 10 mm for stability with capacitive loads. |
| 5 | Negative supply (VCC–) | Accepts down to –15 V; must be referenced to system ground when used in single-supply configurations. |
| 6 | Non-inverting input (Channel B) | Independent input for second signal path; shares no internal coupling with Channel A beyond substrate. |
| 7 | Inverting input (Channel B) | Configurable for independent gain-setting resistors; supports dual active filter topologies. |
| 8 | Output (Channel B) | Electrically isolated from Channel A output; enables stereo audio buffering or dual-sensor signal processing. |
Key Features
| Feature | Design Value |
|---|---|
| Low input offset voltage | 0.5 mV max (TS512A grade) - reduces DC error in precision integrators and transimpedance amplifiers. |
| Wide supply range | Single supply 3–30 V or dual ±1.5–±15 V - eliminates need for external level shifters in mixed-voltage systems. |
| Short-circuit protection | Internal current limiting to 23 mA per channel - prevents latch-up during output fault conditions. |
| High channel separation | 120 dB at 1 kHz - ensures <0.0001% inter-channel leakage in dual-channel audio codecs or data acquisition. |
| Macromodel included | SPICE-compatible behavioral model validated for AC/DC/transient simulation - accelerates loop stability analysis. |
Applications
| Active Telecom Filtering | Automotive Sensor Signal Conditioning |

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 |
|---|---|---|---|
| LM2904VQDR | Lower GBP (1.2 MHz), higher Vio (3 mV max), wider temp range (–40 to +150 °C) | Targeted at cost-sensitive automotive body electronics, not high-fidelity signal paths | Select when budget constraints outweigh bandwidth and offset requirements |
| OPA2182IDR | Zero-drift architecture, 0.012 µV/°C Vio drift, 10 MHz GBP, higher quiescent current (1.3 mA/ch) | Used in high-accuracy data acquisition where long-term drift dominates error budget | Select when microvolt-level DC stability is mandatory and supply current is secondary |
Compared with LM2904VQDR, TS512IYDT offers 2.5× higher bandwidth and 6× lower offset voltage for precision filtering; versus OPA2182IDR, it trades zero-drift performance for lower power (0.6 mA/ch) and proven AEC-Q100 reliability in harsh EMI environments.

FAQ
Is TS512IYDT pin-compatible with TS512IDT?
Yes - both share identical SO-8 pinout and electrical specifications. The "Y" suffix denotes AEC-Q100 qualification and enhanced screening per AEC-Q001/Q002, while TS512IDT is industrial-grade. No PCB redesign is needed when upgrading to automotive qualification.
What is the maximum capacitive load the TS512IYDT can drive without oscillation?
Per Figure 13–15 in the datasheet, TS512IYDT remains stable with up to 100 pF capacitive load across supply voltages from ±4 V to ±15 V when using recommended 100 Ω series output resistance. Larger loads require external isolation or gain reduction to maintain ≥45° phase margin.
Does TS512IYDT support single-supply operation below 5 V?
No - the absolute minimum single-supply voltage is 3 V, but guaranteed performance (e.g., output swing, GBP) begins at 5 V per Table 2. At 3 V, output swing degrades to ±1.5 V and GBP drops to ~1.2 MHz; use only in non-critical biasing or monitoring functions at this voltage.
How does the TS512B variant differ from TS512IYDT in slew rate specification?
TS512IYDT is based on the TS512A version (0.8 V/µs typical slew rate). TS512BIYDT specifies 1.072 V/µs minimum, achieved via process tuning - not pin-compatible due to different ordering codes and test limits, though same SO-8 footprint and pinout.
