Product details
Overview
TS512AIDT 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 (max), ±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 TS512AIDT datasheet, TS512AIDT pinout, TS512AIDT application, or TS512AIDT equivalent, key selection criteria include input offset voltage drift (2 µV/°C), slew rate (0.8 V/µs), ESD protection (2 kV HBM), and guaranteed operation from –40 °C to +125 °C across full supply range.
Technical Context
The TS512AIDT 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 ensures predictable settling and low distortion (<0.03% THD) under capacitive loads up to 100 pF.
It features rail-to-rail output swing (±13 V @ ±15 V supplies), high CMRR (90 dB) and PSRR (90 dB), and matched dual-channel performance - critical for differential signal processing, active filtering, and precision sensor front-ends where inter-channel crosstalk must remain below –120 dB at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - supports stable closed-loop gain ≥10 at 300 kHz with minimal phase margin degradation |
| Input Offset Voltage | ≤500 µV max - enables sub-mV DC accuracy in 12-bit+ data acquisition paths |
| Slew Rate | 0.8 V/µs - sufficient for 10 Vpp signals up to ~100 kHz without slewing distortion |
| Channel Separation | 120 dB @ 1 kHz - prevents crosstalk-induced error in dual-channel instrumentation amplifiers |
| ESD Protection | 2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level robustness in industrial environments |
| Operating Temperature | –40 °C to +125 °C - qualified for automotive under-hood and telecom base station applications |
| Supply Range | ±1.5 V to ±15 V (dual) or 3 V to 30 V (single) - supports wide-input power rails in mixed-signal systems |
Pinout & Package
TS512AIDT 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; bias current ≤300 nA |
| 2 | Non-inverting Input (Channel A) | Common-mode input range extends to within 1.5 V of rails - supports wide dynamic range sensing |
| 3 | Output (Channel A) | Capable of ±13 V swing into 2 kΩ load; short-circuit protected to 23 mA continuous |
| 4 | VCC+ | Positive supply terminal; accepts up to +15 V (dual) or +30 V (single); thermal resistance θj-a = 125 °C/W |
| 5 | VCC− | Negative supply terminal; accepts down to –15 V (dual) or GND (single); referenced for all internal biasing |
| 6 | Non-inverting Input (Channel B) | Matched to Pin 2 in offset, drift, and impedance - essential for differential pair stability |
| 7 | Inverting Input (Channel B) | Electrically symmetrical to Pin 1; enables identical feedback topology for both channels |
| 8 | Output (Channel B) | Independent output stage; channel separation >120 dB ensures no signal coupling at audio frequencies |
Key Features
| Feature | Design Value |
|---|---|
| Internal Phase Compensation | Enables stable unity-gain follower operation without external compensation capacitors |
| Low Input Bias Current | 150 nA typ. - minimizes voltage error across high-impedance sensor interfaces (e.g., piezoelectric transducers) |
| High Channel Separation | 120 dB @ 1 kHz - preserves signal integrity in dual-channel active filters and stereo instrumentation |
| Macromodel Inclusion | SPICE-compatible model provided - accelerates simulation validation of loop stability and transient response |
| Wide Supply Flexibility | Operates from ±1.5 V to ±15 V or 3 V to 30 V - simplifies design reuse across battery-powered and line-powered systems |

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 |
|---|---|---|---|
| TL072CDR | Higher Vio (6 mV max), lower GBP (3 MHz typ. but not guaranteed), no 125 °C rating | Limited to commercial temperature range (0 to 70 °C); unsuitable for extended industrial or automotive use | Select only for cost-sensitive, non-extended-temperature designs where offset drift is not critical |
| OPA2182IDR | Lower Vio (4 µV max), zero-drift architecture, higher cost, SO-8 but different pinout | Requires PCB redesign due to non-pin-compatible layout; overqualified for basic active filtering | Choose only when sub-10 µV offset and near-zero drift are mandatory - not a drop-in replacement |
Compared with TL072CDR and OPA2182IDR, TS512AIDT uniquely balances precision (≤500 µV Vio), extended temperature operation (–40 to +125 °C), SO-8 pin compatibility, and proven stability in unity-gain configurations - making it optimal for telecom and industrial signal chains where reliability and layout continuity matter.

FAQ
Is TS512AIDT pin-compatible with TS512IDT and TS512BIYDT?
Yes - all TS512x variants share identical SO-8 pinout and footprint per Figure 22 in the datasheet. The 'A' grade guarantees ≤500 µV input offset voltage (vs. ≤1.5 mV for standard TS512), while TS512BIYDT adds automotive qualification (AEC-Q100) but retains same pin mapping and electrical interface.
Does TS512AIDT support single-supply operation below 5 V?
No - the absolute minimum single-supply voltage is 3 V, but functional operation below 5 V is not characterized. Electrical characteristics tables specify VCC ≥6 V for guaranteed performance; at 3–4 V, output swing, GBP, and slew rate degrade significantly and are not tested per datasheet Table 2.
Can TS512AIDT drive 100 pF capacitive loads stably in unity-gain configuration?
Yes - Figures 13–15 confirm stable phase margin (>55°) and minimal peaking with 100 pF loads across VCC = 6 V to 30 V. Internal compensation eliminates need for external isolation resistors, unlike many general-purpose op-amps requiring Riso ≥100 Ω for similar loads.
What is the maximum output current per channel under short-circuit conditions?
The datasheet specifies 23 mA continuous short-circuit output current per channel (Table 3). This is thermally limited - sustained short-circuit operation above ambient 25 °C requires derating per θj-a = 125 °C/W, and internal short-circuit protection prevents latch-up or permanent damage.
