The ADA4922-1 is a high voltage, differential 18-bit ADC driver that provides single-ended input and can produce differential output signals in excess of 40 V p-p. It features a 38 MHz bandwidth and a 200 ns fast settling time.
The ADA4922-1 is a differential driver designed for 16-bit to 18-bit ADCs with differential input ranges up to +20 V. Configured as an easy-to-use, single-ended-to-differential amplifier, it requires no external components to drive ADCs and provides essential benefits such as low distortion and high SNR.
The device operates over a wide supply voltage range of 5 V to 26 V with a fixed differential gain of 2. It is available in space-saving 3 mm x 3 mm LFCSP and 8-lead SOIC packages, both equipped with an exposed paddle for efficient heat transfer.
