Product details
Overview
TSV912AQDGKRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified rail-to-rail input/output operational amplifier designed for automotive signal conditioning. 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 low-side current sensing in HEV/EV motor control systems.
For engineers reviewing the TSV912AQDGKRQ1 datasheet, TSV912AQDGKRQ1 pinout, TSV912AQDGKRQ1 application, or TSV912AQDGKRQ1 equivalent, key selection criteria include its ±0.5 µV/°C offset drift, 1 pA typical input bias current, rail-to-rail operation down to 2.5 V, and integrated RFI-EMI rejection filter for robustness in noisy automotive environments.
Technical Context
The TSV912AQDGKRQ1 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 unity-gain stable class-AB output stage enables 20 mV output swing to rails under 10 kΩ load.
It features an integrated RFI-EMI rejection filter, no phase reversal during overdrive, and ±4-kV HBM ESD protection. The device maintains 80 dB CMRR over –40°C to 125°C and exhibits 55° phase margin with 100 pF capacitive load, supporting stable operation in high-impedance sensor interfaces and active filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - supports closed-loop amplification up to ~700 kHz at G = 10 without significant gain roll-off. |
| Slew Rate | 4.5 V/µs - enables accurate reproduction of 100-kHz, 1-Vpp signals with minimal distortion. |
| Input Offset Voltage (max) | ±1.85 mV - ensures ≤0.037% error in 5-V full-scale unidirectional current-sense applications. |
| Input Bias Current (typ) | 1 pA - allows use with >100-MΩ source impedances (e.g., piezoelectric sensors) without significant DC error. |
| Supply Voltage Range | 2.5 V to 5.5 V - compatible with automotive 3.3-V and 5-V domains, including post-regulated battery rails. |

Pinout & Package
DGK package: 8-pin VSSOP (3.00 mm × 4.90 mm), thermally enhanced, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives ADC input or next-stage filter; rail-to-rail swing supports full dynamic range utilization. |
| 2 | IN1– | Inverting input, channel A - connects to shunt resistor low-side node in current-sense configurations. |
| 3 | IN1+ | Noninverting input, channel A - referenced to ground or bias network; high-impedance input minimizes loading. |
| 4 | V– | Negative supply or ground - serves as common reference for single-supply operation; must be low-impedance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier 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, SOIC-8 package. | Better suited for DC-coupled sensor interfaces where speed is secondary to ultra-low power. | Select when system bandwidth <200 kHz and quiescent current budget is tighter than 550 µA/channel. |
| TSZ122IYDT | Higher precision (±30 µV max VOS), lower noise (12 nV/√Hz), but only 1.7 MHz GBW and non-automotive grade. | Targeted at industrial test equipment; lacks AEC-Q100 qualification and extended temperature support. | Choose only for non-automotive designs requiring sub-100-µV offset and where 125°C operation is not required. |
Compared with LMV932QDRQ1 and TSZ122IYDT, the TSV912AQDGKRQ1 uniquely balances 8-MHz bandwidth, rail-to-rail operation, and AEC-Q100 Grade 1 compliance in a thermally optimized VSSOP package-making it optimal for time-critical automotive sensing where both speed and ruggedness are mandatory.

FAQ
What is the maximum operating junction temperature for TSV912AQDGKRQ1?
The TSV912AQDGKRQ1 has a maximum junction temperature of 150°C, with specified operation up to +125°C ambient. Its DGK (VSSOP) package achieves a junction-to-board thermal resistance (RθJB) of 120.3°C/W, enabling reliable operation in under-hood applications when mounted on 2-oz copper PCBs with adequate thermal relief.
Does TSV912AQDGKRQ1 support single-supply operation?
Yes, TSV912AQDGKRQ1 fully supports single-supply operation from 2.5 V to 5.5 V. Its rail-to-rail input extends 100 mV beyond both supply rails, and its output swings to within 20 mV of V– and V+ under 10-kΩ load-enabling direct interfacing with 3.3-V ADCs without external level-shifting circuitry.
How does the RFI-EMI rejection filter in TSV912AQDGKRQ1 improve system robustness?
The integrated RFI-EMI rejection filter in TSV912AQDGKRQ1 attenuates >30 dB of RF interference above 100 MHz, as verified by EMIRR+ testing. This prevents demodulation of GSM, Bluetooth, or radar-band noise into baseband signals-critical for maintaining accuracy in ADAS camera power monitors and infotainment microphone preamps exposed to vehicle RF emissions.
Can TSV912AQDGKRQ1 drive capacitive loads without instability?
TSV912AQDGKRQ1 remains stable with up to 100 pF capacitive load at unity gain, exhibiting 55° phase margin per datasheet Figure 7-31. For loads >100 pF, external series resistance (≥10 Ω) at the output is recommended to maintain stability in motor current sensing applications with long PCB traces or cable-driven outputs.
What is the overload recovery time specification for TSV912AQDGKRQ1?
The TSV912AQDGKRQ1 has a typical overload recovery time of 200 ns, defined as the time required to return from saturation to linear operation. This fast recovery enables accurate current measurement during high-frequency PWM switching in HEV inverter phase-leg monitoring, minimizing dead-time-induced measurement gaps.
