Frequently Asked Questions
What is the INA148UA and what does it do?
The INA148UA is a precision difference amplifier from Texas Instruments that provides unity gain (1 V/V) with a minimum 100dB common-mode rejection ratio (CMRR). It requires no external resistors and operates from a 4.5V to 36V single supply or dual supply, making it ideal for rejecting common-mode noise in industrial signal conditioning circuits.
What package is the INA148UA and how many pins does it have?
The INA148UA comes in an 8-pin SOIC-8 (Small Outline IC) surface-mount package. The UA suffix in TI naming convention denotes this SOIC-8 footprint. The compact package suits space-constrained PCB designs in industrial and test equipment.
What is the operating temperature range of the INA148UA?
The INA148UA is rated for an extended industrial temperature range of -40 degrees C to +125 degrees C, making it suitable for harsh environmental conditions in automotive, industrial control, and outdoor equipment applications.
What are common alternatives to the INA148UA?
Common pin-compatible or functionally equivalent alternatives to the INA148UA include the INA143UA (selectable 0.1x/10x gain), AD629 from Analog Devices (high common-mode voltage difference amplifier), and the INA149 (high common-mode range difference amplifier). Always verify supply voltage range, CMRR, and package compatibility before substituting.
Is the INA148UA RoHS compliant and what is the minimum order quantity?
Yes, the INA148UA is RoHS compliant and lead-free. The minimum order quantity (MOQ) is 1 piece, available at tiered pricing from $5.38 per unit down to $1.23 at volume (200+ units). Global shipping is supported.
