INA849DR Information

INA849DR X-Ray Inspection

X-Ray inspection ensures product integrity by detecting internal defects without damaging external packaging. It reduces failure rates and enhances production efficiency, making it indispensable in the electronics components industry.

Description

The Texas Instruments INA849DR is a precision instrumentation amplifier designed for low-power, high-precision applications. It features ultra-low noise, precise super-beta input performance, and a wide bandwidth of 28 MHz (G = 1). This amplifier is suitable for industrial automation, test and measurement equipment, battery monitoring systems, and sensor signal conditioning applications. Its low power consumption and compact package make it an ideal choice for portable devices and space-constrained designs. The INA849DR operates over a specified temperature range of -40°C to +125°C and is available in 8-pin SOIC and VSSOP packages.

Features

The INA849DR features include:

Ultra-low noise: 1-nV/√Hz input voltage noise (typical)
Precision super-beta input performance with low offset voltage, drift, and bias current
High bandwidth: 28 MHz (G = 1), 8 MHz (G = 100)
Slew rate: 35 V/µs
Common-mode rejection: 120 dB (minimum) for maximum gain
Low power consumption
Specified temperature range: –40°C to +125°C

These features make the INA849DR suitable for industrial automation, test and measurement equipment, battery monitoring systems, sensor signal conditioning applications, data acquisition systems, control systems, and instrumentation amplifiers.
