Texas Instruments OPA188AIDBVR Datasheet
The OPA188AIDBVR is a single-channel, high-voltage, zero-drift operational amplifier leveraging proprietary auto-zeroing technology. It delivers an ultra-low maximum offset voltage of 25 uV, near-zero temperature drift (0.03 uV/°C typical), low broadband noise (8.8 nV/sqrt(Hz)), and zero flicker noise (0.1 Hz to 10 Hz noise of 0.25 uV peak-to-peak). Operating across a wide supply voltage range from 4 V to 36 V (± V to ±18 V), this precision amplifier features rail-to-rail output swing and an input common-mode range that includes the negative supply rail.
The OPA188AIDBVR is currently In Stock and ready for immediate shipping at ICHOME. As a leading independent distributor, we ensure 100% authenticity, full traceable compliance, and rapid global delivery to safeguard your procurement pipeline against production delays.

Drop-in & Functional Alternatives of OPA188AIDBVR
OPA2188AIDR / OPA2188: Dual-channel functional equivalent in an 8-pin SOIC package for designs requiring multiple zero-drift amplifiers on a single board.
OPA333AIDBVR: A low-voltage (1.8 V to 5.5 V), ultra-low power alternative (17 uA) for battery-powered applications where high-voltage (36 V) operation is not required.
Key Application of TI OPA188AIDBVR
Industrial Automation & Test: Analog input modules, data acquisition systems (DAQ), and precision DC power supplies.
Precision Measurement: Electronic weigh scales, strain gauge bridges, and RTD temperature transmitters with active linearization.
Current Sensing: High-side / low-side voltage-to-current converters and current-monitoring circuits.
Package Dimensions (SOT-23-5) of OPA188AIDBVR
The DBV package features a 5-pin SOT-23 plastic footprint measuring 2.90 mm x 1.60 mm (body size) with a max height of 1.45 mm.
What Is the Main Difference Between OPA188AIDBVR and OPA188AIDBVT?
Both part numbers refer to the exact same integrated circuit (OPA188 zero-drift op amp in a 5-pin SOT-23 package) with identical electrical performance, pinouts, and industrial temperature ratings.
The sole distinction lies in the reel packaging quantity: OPA188AIDBVR designates a standard large tape & reel quantity of 3,000 pieces, whereas OPA188AIDBVT designates a small tape & reel quantity of 250 pieces.
