INA500AIDBVR

Instrumentation, Op Amps, Buffer Amps Overview

The INA500AIDBVR is a low-power, cost-optimized difference amplifier from Texas Instruments. It operates on a single supply voltage ranging from 1.7V to 5.5V and features an ultra-high input impedance exceeding 1MΩ. The device offers three fixed gain options: G = 1, 0.50, and 0.25. Key electrical specifications include a typical bandwidth of 125kHz, a quiescent current of 13.5µA at 5.5V, and a maximum offset voltage of 3.5mV in the G = 1 configuration. It provides a minimum common-mode rejection ratio (CMRR) of 75dB and can drive up to 200pF load capacitance.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Ultra-high input impedance exceeding 1MΩ minimizes signal loading effects.
• Integrated precision matched resistors eliminate the need for external discrete components.
• Low power consumption with a quiescent current as low as 13.5µA.
• Space-saving SC-70 package design suitable for compact applications.

Instrumentation, Op Amps, Buffer Amps Applications

• Level translation circuits
• Battery monitoring systems
• Interfacing with low-speed analog-to-digital converters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'DBVR' corresponds to the SOT-23-6 package and reel packaging format. Confirm that the 'A' version meets the required offset and CMRR specifications for your application. Ensure the operating temperature range aligns with industrial requirements. Check for any recent documentation updates or pinout revisions before finalizing the procurement order.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and low power are critical constraints. The fixed gain options simplify circuit design by removing external resistor tolerances. Consider the SC-70 package size if board space is limited. Verify that the 125kHz bandwidth is sufficient for the signal frequencies involved. Ensure the supply voltage range matches the system's available power rails.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA500 family of difference amplifiers designed for cost and size optimization. The 'A' suffix denotes specific performance grades regarding offset voltage and CMRR. The 'DCKR' variant uses an SC-70 package, while the 'DBVR' variant utilizes a SOT-23-6 package. Both packages offer surface-mount installation for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the same family include INA500ADCKR and INA500BDCKR, which share identical pinouts but may differ in performance grades. Cross-family replacements require careful evaluation of gain accuracy, input impedance, and package dimensions to ensure compatibility.
