Texas Instruments OPA607QDBVRQ1

Overview

OPA607QDBVRQ1 from Texas Instruments is an automotive-grade, decompensated CMOS operational amplifier optimized for low-voltage, high-bandwidth signal conditioning. It delivers 50 MHz gain-bandwidth product, 24 V/µs slew rate, rail-to-rail output swing within 8 mV of supply rails, and operates from 2.2 V to 5.5 V across –40°C to +125°C. It serves as a precision transimpedance or low-side current-sensing amplifier in motor control and DC/DC converter feedback loops.

For engineers reviewing the OPA607QDBVRQ1 datasheet, OPA607QDBVRQ1 pinout, OPA607QDBVRQ1 application, or OPA607QDBVRQ1 equivalent, key selection criteria include minimum stable gain (6 V/V), input offset drift ≤1.5 µV/°C, 3.8 nV/√Hz voltage noise, AEC-Q100 Grade 1 qualification, and SOT-23-5 package compatibility with space-constrained automotive PCB layouts.

Technical Context

The OPA607QDBVRQ1 uses a decompensated CMOS architecture requiring ≥6 V/V noise gain for stability, enabling higher bandwidth and lower distortion than unity-gain-stable counterparts at comparable quiescent current. Its input stage features ultra-low bias current (≤10 pA) and wide common-mode range (to VS–), supporting high-impedance sensor interfaces like piezoelectric transducers.

Rail-to-rail output capability ensures full dynamic range utilization into successive ADC stages, while internal ESD protection (±2000 V HBM) and robust capacitive load drive (up to 47 pF without isolation resistor) simplify design in noisy automotive environments.

FAQ

What is the minimum stable gain for OPA607QDBVRQ1?

The OPA607QDBVRQ1 requires a minimum noise gain of 6 V/V (15.56 dB) for stable operation. This decompensated architecture enables its 50 MHz gain-bandwidth product and 24 V/µs slew rate at low quiescent current. Operating below this gain risks oscillation due to insufficient phase margin; verified stability data confirms ≥65° phase margin at G = 6 V/V per the official datasheet.

Is OPA607QDBVRQ1 qualified for automotive use?

Yes, OPA607QDBVRQ1 is AEC-Q100 qualified for Grade 1 (–40°C to +125°C ambient), with full characterization across temperature, supply voltage, and lifetime stress testing. It meets automotive reliability standards including HTOL, TC, and ESD (±2000 V HBM), and is manufactured in TI's IATF 16949-certified facilities-making OPA607QDBVRQ1 suitable for safety-critical ADAS, powertrain, and body electronics.

What is the maximum capacitive load OPA607QDBVRQ1 can drive without external compensation?

OPA607QDBVRQ1 can drive up to 47 pF of capacitive load directly on its output while maintaining ≥45° phase margin-no series isolation resistor required. Beyond 47 pF, TI recommends adding an RISO resistor (value selected from Figure 7-18 of the datasheet) between the output and load to restore stability. This capability simplifies layout in compact automotive modules where parasitic capacitance from long traces or ADC inputs must be managed.

Does OPA607QDBVRQ1 support single-supply operation?

Yes, OPA607QDBVRQ1 fully supports single-supply operation from 2.2 V to 5.5 V. Its input common-mode range extends to the negative rail (VS–), and its rail-to-rail output swings within 8 mV of both supply rails-enabling true single-supply functionality in 3.3 V or 5 V automotive domains. The device operates correctly with VS– tied to GND and VS+ connected to the positive rail, eliminating need for split supplies in most sensing applications.

What packaging and thermal characteristics apply to OPA607QDBVRQ1?

OPA607QDBVRQ1 is supplied in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm. Its thermal metrics include RθJA = 196.5°C/W (JEDEC standard board), RθJC(top) = 118.7°C/W, and RθJB = 64.5°C/W-indicating effective heat transfer to PCB copper. This package is qualified for reflow soldering per J-STD-020 and supports automotive under-hood thermal cycling requirements when mounted on adequately sized thermal pads.
