Product details
Overview
TSB612IDT from STMicroelectronics is a dual, rail-to-rail output, low-power operational amplifier optimized for industrial and automotive signal conditioning. It delivers 560 kHz gain bandwidth product, 1 mV max input offset voltage, 125 µA max supply current per channel at 36 V, and operates across ±0.1 V to (VCC+ − 1 V) input common-mode range - enabling precision sensing in 24 V battery monitoring circuits.
For engineers reviewing the TSB612IDT datasheet, TSB612IDT pinout, TSB612IDT application, or TSB612IDT equivalent, this page provides verified pin functions, real-world application cards for battery management and power supply feedback, confirmed alternatives with documented performance trade-offs, and supply-chain support for AEC-Q100-aligned production programs.
Technical Context
The TSB612IDT integrates two independent amplifiers in a single SO8 package, each featuring unity-gain stability, rail-to-rail output swing (within 100 mV of VCC+ and 110 mV of VCC− at 36 V), and input common-mode range extending to ground. Its architecture supports operation from 2.7 V to 36 V with guaranteed specs across −40 °C to +125 °C.
It achieves high PSRR (124 dB typ. at 12 V) and CMRR (130 dB typ. at 36 V), with low 1.3–6 µV/°C input offset drift and 29 nV/√Hz input noise at 1 kHz (36 V). The device is ESD-hardened to 4 kV HBM and qualified per AEC-Q100 Grade 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 36 V - enables direct interface with 12 V/24 V automotive rails and industrial 3.3–36 V systems without level-shifting. |
| Gain Bandwidth Product | 560 kHz typ. at 36 V - supports stable closed-loop gain up to ~50× at DC–10 kHz for sensor amplification and error amplification. |
| Input Offset Voltage | 1 mV max - ensures ≤0.5% full-scale error in 200 mV reference-based current-sense applications at room temperature. |
| Supply Current per Channel | 125 µA max at 36 V - allows dual-channel operation under 250 µA total, critical for always-on automotive modules. |
| Input Common-Mode Range | VCC− − 0.1 V to VCC+ − 1 V - permits direct sensing of signals referenced to ground in high-side current monitors. |
| Rail-to-Rail Output | Swings within 100 mV of VCC+, 110 mV of VCC− (36 V, 10 kΩ load) - maximizes dynamic range in single-supply data acquisition stages. |
| ESD Rating | 4 kV HBM - meets IEC 61000-4-2 Level 3 system-level robustness requirements for automotive ECUs. |
Pinout & Package
TSB612IDT is housed in an SO8 (Small Outline Integrated Circuit, 8-pin) package with standard 1.27 mm pitch, RoHS-compliant and ECOPACK2 qualified. Thermal resistance RthJA is 125 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Delivers rail-to-rail buffered signal; must drive ≤10 kΩ load for full spec compliance. |
| 2 (IN−1) | Inverting input, Amp 1 | Accepts differential or single-ended feedback; input bias current ≤10 nA (max, −40 °C to 125 °C). |
| 3 (IN+1) | Non-inverting input, Amp 1 | Supports ground-referenced inputs; common-mode range includes VCC− (ground). |
| 4 (VCC−) | Negative supply rail | Typically connected to GND in single-supply configs; serves as reference for both amplifiers. |
| 5 (VCC+) | Positive supply rail | Accepts 2.7–36 V; bypass capacitor (22 nF) required near pin for stable startup and PSRR optimization. |
| 6 (IN−2) | Inverting input, Amp 2 | Independent of Amp 1; shares same supply pins but has separate input/output paths. |
| 7 (IN+2) | Non-inverting input, Amp 2 | Enables dual-channel signal conditioning (e.g., current + voltage sense in DC-DC converter). |
| 8 (OUT2) | Amplifier 2 output | Provides second rail-to-rail output; no crosstalk specification given, but layout isolation recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Low quiescent current | 125 µA max per channel at 36 V - enables dual-opamp functionality in <300 µA system standby budgets. |
| Rail-to-rail output stage | Output swing within 100 mV of VCC+ and 110 mV of VCC− at 36 V - preserves >95% of available voltage headroom for ADC interfacing. |
| Extended temperature operation | Guaranteed performance from −40 °C to +125 °C - qualified for engine bay and transmission control unit deployment. |
| High CMRR & PSRR | 130 dB CMRR and 124 dB PSRR (typ., 36 V) - suppresses noise coupling in noisy 12/24 V power domains. |
| Automotive qualification | AEC-Q100 Grade 1 compliant - validated for reliability in automotive electronics per JEDEC JESD47 stress testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, rail-to-rail output, high-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB611IDT | Single-channel version, identical electrical specs and package footprint. | Used where only one amplifier is needed; saves board space vs. unused channel on TSB612IDT. | Select when BOM simplification or lower channel count suffices; pin-compatible drop-in replacement for Amp 1 path. |
| LM2904BQDR | Wider supply range (up to 36 V), but higher 3 mV offset, 700 kHz GBP, and non-rail-to-rail output (1.5 V headroom). | Suitable for cost-sensitive non-precision applications; lacks AEC-Q100 qualification. | Choose for legacy designs or non-automotive use where offset and output swing are less critical. |
Compared with TSB612IDT, TSB611IDT offers identical performance in half the channel count and footprint, while LM2904BQDR trades precision and rail-to-rail capability for broader vendor availability and lower unit cost - making it viable only in non-safety-critical, non-temperature-extreme contexts.

FAQ
Is TSB612IDT pin-compatible with other ST dual op-amps like TS912 or TSV912?
No. TSB612IDT uses a non-standard SO8 pinout: OUT1–IN−1–IN+1–VCC−–VCC+–IN−2–IN+2–OUT2. TS912 and TSV912 follow industry-standard dual-opamp pinout (IN−1–IN+1–VCC−–OUT1–OUT2–IN+2–IN−2–VCC+), making them mechanically and electrically incompatible without PCB redesign.
Can TSB612IDT drive a 100 pF capacitive load without oscillation?
Yes - the datasheet confirms ≥60° phase margin with 100 pF load at all supply voltages (2.7 V, 12 V, 36 V) and temperatures (−40 °C to +125 °C), provided a 22 nF bypass capacitor is placed at the VCC+ pin. No external compensation is required for stability under these conditions.
What is the maximum output current capability of TSB612IDT at 36 V supply?
At 36 V supply and 25 °C, TSB612IDT delivers ±60 mA short-circuit output current (Isource = 70 mA max, Isink = 60 mA max). Derating applies above 25 °C: output current drops to ±10 mA at 125 °C ambient due to thermal limits and junction temperature constraints.
Does TSB612IDT support true single-supply operation with input referenced to ground?
Yes. Its input common-mode range extends to VCC− − 0.1 V (i.e., ground when VCC− = 0 V), and rail-to-rail output swings within 110 mV of ground. This enables ground-referenced sensor interfaces (e.g., thermistor dividers) without level-shifting circuitry in 3.3 V to 36 V single-rail systems.
