Product details
Overview
TSV912AQDRQ1 from Texas Instruments is a dual-channel automotive-grade rail-to-rail input/output operational amplifier optimized for AEC-Q100 Grade 1 applications. It delivers 8 MHz gain bandwidth, 4.5 V/µs slew rate, and 550 µA per channel quiescent current at 2.5–5.5 V supply, enabling precision signal conditioning in HEV/EV motor control and ADAS current-sensing circuits.
For engineers reviewing the TSV912AQDRQ1 datasheet, TSV912AQDRQ1 pinout, TSV912AQDRQ1 application, or TSV912AQDRQ1 equivalent, this page provides verified specifications, SOIC-8 package layout, automotive temperature range (–40°C to 125°C), low 1.85 mV max input offset voltage, and validated alternatives for infotainment, body electronics, and powertrain sensing designs.
Technical Context
The TSV912AQDRQ1 employs a complementary differential input stage-N-channel and P-channel pairs-to achieve rail-to-rail input operation across its full 2.5–5.5 V supply range, with common-mode voltage extending 100 mV beyond both rails. Its class AB output stage enables rail-to-rail output swing within 20 mV of supply rails under 10 kΩ load.
It is unity-gain stable, features integrated RFI-EMI rejection filtering, no phase reversal during overdrive, and ±4-kV HBM ESD protection. The device supports single-supply operation and maintains low input bias current (1 pA typ) and low offset drift (±0.5 µV/°C typ), making it suitable for high-impedance sensor interfaces and active filtering in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - Enables stable closed-loop operation up to 100 kHz with G = 100, supporting fast ADC driver and filter applications. |
| Slew Rate | 4.5 V/µs - Supports 2-V step response settling to 0.1% in 0.5 µs, critical for transient-critical current sensing. |
| Input Offset Voltage (max) | ±1.85 mV at TA = 25°C - Ensures ≤1.85 mV error in unidirectional low-side shunt monitoring at 5 V supply. |
| Quiescent Current per Channel | 550 µA (typ) at VS = 5.5 V - Allows dual-channel operation at <1.2 mA total, ideal for always-on automotive subsystems. |
| Rail-to-Rail I/O | Input extends (V−) − 0.1 V to (V+) + 0.1 V; output swings to within 20 mV of rails - Maximizes dynamic range in 3.3 V or 5 V single-supply systems. |
| Operating Temperature Range | –40°C to 125°C - Qualified per AEC-Q100 Grade 1, enabling use in engine bay, battery management, and ADAS ECUs. |
| ESD Rating (HBM) | ±4 kV - Meets automotive board-level robustness requirements without external protection circuitry. |
Pinout & Package
TSV912AQDRQ1 is packaged in an 8-pin SOIC (D package), 4.90 mm × 6.00 mm body size, with standard lead finish and moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - Drives downstream ADC input or feedback network; rail-to-rail swing supports full-scale analog capture. |
| 2 | IN1− | Inverting input, channel A - Accepts feedback or inverted signal path; high impedance (1 pA bias) minimizes loading on high-Z sources. |
| 3 | IN1+ | Noninverting input, channel A - Used for reference-based sensing (e.g., shunt voltage); rail-to-rail CMVR allows direct connection to ground-referenced signals. |
| 4 | V− | Negative supply / ground - Serves as return path for single-supply operation; must be low-impedance to maintain PSRR >80 dB. |
| 5 | IN2+ | Noninverting input, channel B - Enables dual-sensor monitoring (e.g., phase current + bus voltage) with matched DC performance. |
| 6 | IN2− | Inverting input, channel B - Supports differential configuration for noise rejection in motor control feedback loops. |
| 7 | OUT B | Amplifier B output - Independent output for parallel signal paths; no crosstalk (100 dB channel separation at DC). |
| 8 | V+ | Positive supply - Accepts 2.5–5.5 V; internal regulation ensures stable biasing across automotive battery transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with 100-mV beyond rails | Enables direct interface to ground-referenced sensors and 0–5 V microcontroller inputs without level-shifting. |
| Low 18 nV/√Hz input voltage noise at 1 kHz | Preserves SNR in precision current sensing (e.g., 100 µΩ shunt at 10 A), limiting noise contribution to <10 µV RMS in 10 kHz BW. |
| Integrated RFI-EMI rejection filter | Attenuates >40 dB of GSM/ISM-band interference (e.g., 900 MHz, 2.4 GHz), eliminating need for external ferrite beads in infotainment PCBs. |
| No phase reversal under overdrive | Prevents latch-up or erroneous control signals during input transients (e.g., load dump), ensuring functional safety in motor drivers. |
| Unity-gain stable with capacitive load drive | Drives up to 300 pF directly (e.g., ADC sample capacitor + trace capacitance) without external compensation or isolation resistor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932QDRQ1 | Lower GBW (1.5 MHz), higher IQ (120 µA/channel), same AEC-Q100 Grade 1 rating and SOIC-8 package. | Better suited for low-speed sensor buffering (e.g., cabin temperature) where bandwidth <200 kHz suffices. | Select when power budget is tighter than speed requirement; not suitable for 100-kHz current loop control. |
| OPA2991QDGKRQ1 | Higher GBW (102 MHz), higher IQ (1.1 mA/channel), lower VOS (±125 µV max), same –40°C to 125°C range. | Targeted at high-speed ADAS radar signal chain or high-resolution encoder interfaces requiring >10-MHz closed-loop bandwidth. | Select when >10× bandwidth margin is required; avoid if system-level power budget restricts per-channel IQ to <600 µA. |
Compared with LMV932QDRQ1, TSV912AQDRQ1 offers 5.3× higher bandwidth at only ~4.6× higher quiescent current; versus OPA2991QDGKRQ1, it reduces IQ by 67% while retaining sufficient speed for most automotive current sensing and sensor signal chains.

FAQ
What is the maximum input common-mode voltage range for TSV912AQDRQ1?
The TSV912AQDRQ1 supports rail-to-rail input with a common-mode voltage range from (V−) − 0.1 V to (V+) + 0.1 V across its full 2.5–5.5 V supply range. This allows direct interfacing with ground-referenced sensors and logic-level signals without external level-shifting circuitry, and is confirmed in Section 7.7 Electrical Characteristics of the official datasheet SBOSA18C.
Does TSV912AQDRQ1 require external compensation for unity-gain stability?
No, TSV912AQDRQ1 is internally compensated and unity-gain stable. It drives capacitive loads up to 300 pF without oscillation, as verified in Figure 7-22 (Small-Signal Overshoot vs Load Capacitance) and Section 8.4 of the datasheet. This eliminates the need for external compensation networks in typical ADC driver or filter applications.
What is the guaranteed maximum input offset voltage for TSV912AQDRQ1 over temperature?
The guaranteed maximum input offset voltage for TSV912AQDRQ1 is ±3 mV over the full operating temperature range of –40°C to 125°C, as specified in Table 7-7 (Electrical Characteristics) under "OFFSET VOLTAGE" parameter at TA = –40°C to 125°C. This value ensures predictable error bounds in precision current-sensing implementations.
Can TSV912AQDRQ1 operate from a single 3.3-V supply?
Yes, TSV912AQDRQ1 is fully specified for single-supply operation from 2.5 V to 5.5 V. At 3.3 V, it maintains rail-to-rail input/output swing, 8 MHz GBW, and 550 µA typical quiescent current per channel-making it ideal for 3.3-V automotive microcontroller peripheral signal conditioning, as confirmed in Section 7.3 Recommended Operating Conditions.
Is TSV912AQDRQ1 pin-compatible with other devices in the TSV91x-Q1 family?
TSV912AQDRQ1 shares identical pinout (SOIC-8) with all dual-channel variants in the TSV91x-Q1 family-including TSV912A-Q1 in D, DGK, and PW packages-but is not pin-compatible with single-channel (TSV911A-Q1) or quad-channel (TSV914A-Q1) members due to differing channel count and pin assignments, as documented in Tables 6-2 and 5 of SBOSA18C.
