Frequently Asked Questions
What is the gain of the INA146UA?
The INA146UA has a fixed gain of 1 V/V (unity gain) with a tight gain accuracy of 0.02% (200ppm). This is set by an internal precision resistor network, eliminating the need for external gain-setting resistors and ensuring consistent performance across production.
What supply voltage does the INA146UA require?
The INA146UA operates from a dual (split) supply ranging from ±2.25V to ±18V, with ±15V being the typical operating voltage. It does not support single-supply operation, so a bipolar power rail is required in your design.
What package and pin count does the INA146UA come in?
The INA146UA is available in an 8-pin SOIC package (small-outline IC). The 'UA' suffix designates the SOIC-8 package. Pin 1 and Pin 8 are the inverting and non-inverting inputs; Pin 6 is the output. Refer to the TI datasheet for the complete pinout diagram.
What are typical applications for the INA146UA?
Typical applications include industrial data acquisition, bridge sensor amplification, motor drive feedback, high-side current sensing, and medical instrumentation front-ends. Its 80dB CMRR makes it especially effective at rejecting power-line noise in noisy industrial environments.
What is the minimum order quantity and price for INA146UA?
The INA146UA is available with MOQ 1. Pricing starts at $5.92 for single units, dropping to $1.49 at 135 pieces, $1.43 at 175 pieces, and $1.38 at 218 pieces. Stock is available for immediate inquiry and worldwide shipping.
