Product details
Overview
TSB512IYDT from STMicroelectronics is a dual-channel rail-to-rail input/output operational amplifier optimized for high-side and low-side current sensing, motor control, and industrial process control. It delivers 6 MHz gain bandwidth, 3 V/µs slew rate, 1.5 mV max input offset voltage, and operates from 2.7 V to 36 V single supply (±1.35 V to ±18 V dual). Its integrated EMI filter and 2 kV HBM ESD rating support robust operation in noisy industrial environments.
For engineers reviewing the TSB512IYDT datasheet, TSB512IYDT pinout, TSB512IYDT application, or TSB512IYDT equivalent, key selection criteria include its wide supply range, rail-to-rail I/O swing at high voltage, low noise (12 nV/√Hz), extended temperature capability (–40 °C to +125 °C), and automotive-grade qualification per AEC-Q100.
Technical Context
The TSB512IYDT implements a dual-channel CMOS-input op-amp architecture with independent input stages capable of common-mode voltage operation from VCC– – 0.2 V to VCC+ + 0.2 V. Its unity-gain-stable design supports capacitive load drive up to 100 pF without external compensation.
Each channel features matched DC performance (±2 µV/°C offset drift, 105–125 dB open-loop gain) and AC behavior (4.5–6 MHz GBP, 2.2–3 V/µs slew rate across 5–36 V supply), enabling precise signal conditioning in bidirectional current sensing and closed-loop motor control feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6 MHz typical - enables stable closed-loop operation up to ~500 kHz with gain ≥12 in current-sense amplifiers. |
| Slew Rate | 3 V/µs at 36 V supply - supports fast transient response in motor phase-current monitoring and PWM-based actuator drivers. |
| Input Offset Voltage | ±1.5 mV max at 25 °C - ensures ≤0.5% error in 300 mV full-scale shunt-based current measurement. |
| Supply Voltage Range | 2.7 V to 36 V single supply - eliminates need for level-shifting in 12 V/24 V industrial and automotive power rails. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - maintains SNR >90 dB in precision strain gauge and Hall sensor front-ends. |
| EMI Filtering | Integrated on-chip EMI filter - suppresses RF interference from switching power supplies and motor drives without external RC networks. |
| Temperature Range | –40 °C to +125 °C - qualified for under-hood automotive and factory-floor industrial deployment. |
Pinout & Package
TSB512IYDT is housed in an 8-pin MiniSO8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), RoHS-compliant and ECOPACK® certified. The package supports automated optical inspection and offers thermal resistance (RthJA) of 190 °C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - rail-to-rail swing supports direct interface to SAR ADCs or comparator inputs without level shift. |
| 2 | IN1– | Inverting input for Channel 1 - configured as current-sense amplifier input when used with external gain resistors. |
| 3 | IN1+ | Non-inverting input for Channel 1 - accepts common-mode voltages up to VCC+ + 0.2 V, enabling high-side sensing above supply rail. |
| 4 | VCC– | Negative supply terminal - referenced to system ground in single-supply configurations; enables true dual-supply operation down to ±1.35 V. |
| 5 | IN2+ | Non-inverting input for Channel 2 - electrically isolated from Channel 1; supports independent sensor channels or differential pair configuration. |
| 6 | IN2– | Inverting input for Channel 2 - matched bias current (<±200 nA) ensures <10 µV offset contribution in precision transducer interfaces. |
| 7 | OUT2 | Channel 2 output - independently buffered; allows simultaneous monitoring of two current paths or redundant sensor outputs. |
| 8 | VCC+ | Positive supply terminal - accepts up to +40 V absolute maximum; internal protection clamps prevent latch-up during load-dump transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Output swings within 90 mV of rails at 2 mA load; inputs operate 0.2 V beyond supply rails - enables direct connection to 3.3 V ADCs and high-side shunt topologies. |
| Wide Supply Range | 2.7–36 V single supply - eliminates external regulators in 12 V/24 V systems and supports brown-out tolerant operation down to 2.7 V. |
| Low Input Noise | 12 nV/√Hz @ 10 kHz - preserves resolution in microvolt-level signals from load cells and precision RTDs. |
| Automotive Qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C) - validated for engine control units, battery management, and ADAS power stages. |
| EMI Immunity | On-die EMI filter - reduces susceptibility to 100 MHz–1 GHz RF fields from inverters and wireless modules without board-level shielding. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB712IYDT | Higher precision: ±0.3 mV VIO, 0.5 µV/°C drift, but narrower supply (2.7–20 V) and lower GBP (2.5 MHz) | Preferred for strain gauge bridges and precision weigh scales where offset stability dominates speed requirements | Select TSB712IYDT only if offset drift <0.5 µV/°C is mandatory and supply stays ≤20 V. |
| LM2904QDRQ1 | Wider temp range (–40 °C to +150 °C), but non-rail-to-rail inputs, higher VIO (±3 mV), no integrated EMI filter | Suitable for cost-sensitive automotive body electronics where rail-to-rail I/O is not required | Choose LM2904QDRQ1 only for legacy designs requiring pin compatibility with LM2904 and relaxed noise/EMI specs. |
Compared with TSB712IYDT, the TSB512IYDT trades precision for wider supply range and higher speed-critical for 24 V motor control. Versus LM2904QDRQ1, it adds rail-to-rail I/O and EMI filtering essential for modern high-frequency power systems.

FAQ
What is the maximum capacitive load the TSB512IYDT can drive without instability?
The TSB512IYDT is characterized to drive up to 100 pF capacitive load while maintaining ≥34° phase margin at unity gain. For loads exceeding 100 pF, a series resistor (≥10 Ω) between the output and capacitor is recommended to isolate the reactive load and preserve stability, especially in motor current-sense applications with long PCB traces.
Does the TSB512IYDT support true dual-supply operation?
Yes. The TSB512IYDT operates with split supplies from ±1.35 V to ±18 V. Pin 4 (VCC–) serves as the negative rail and Pin 8 (VCC+) as the positive rail. Common-mode input range extends 0.2 V beyond both rails, enabling use in traditional dual-supply instrumentation circuits without level-shifting networks.
How does the integrated EMI filter function, and what frequencies does it suppress?
The integrated EMI filter is a monolithic RC network fabricated on-die at the input stage, tuned to attenuate RF interference in the 100 MHz–2 GHz range. It reduces susceptibility to radiated emissions from switch-mode power supplies and wireless transceivers without requiring external ferrite beads or RC filters, verified per IEC 61000-4-3 testing.
Is the TSB512IYDT pin-compatible with other devices in the TSB51x family?
No. The TSB512IYDT (MiniSO8) has a unique 8-pin dual-channel pinout distinct from the TSB511 (SOT23-5, single-channel) and TSB514 (TSSOP14, quad-channel). Pin mapping differs across packages: e.g., VCC– is Pin 4 in TSB512 but Pin 2 in TSB511. Direct substitution requires PCB redesign.
