High Voltage, Differential 18-Bit ADC Driver
The ADA4922-1 is a differential driver for 16-bit to 18-bit analog-to-digital converters (ADCs) that have differential input ranges up to ±20 V. Configured as an easy-to-use, single-ended-to-differential amplifier, the ADA4922-1 requires no external components to drive ADCs. The ADA4922-1 provides essential benefits such as low distortion and high SNR that are required for driving ADCs with resolutions up to 18 bits.
With a wide supply voltage range (5 V to 26 V), high input impedance, and fixed differential gain of 2, the ADA4922-1 is designed to drive ADCs found to in a variety of applications, including industrial instrumentation.
The ADA4922-1 is manufactured on Analog Devices, Inc., proprietary, second-generation XFCB process that enables the amplifier to achieve excellent noise and distortion performance on high supply voltages.
The ADA4922-1 is available in an 8-lead 3 mm × 3 mm LFCSP as well as an 8-lead SOIC package. Both packages are equipped with an exposed paddle for more efficient heat transfer. The ADA4922-1 is rated to work over the extended industrial temperature range, −40°C to +85°C.
