| Model Number | ADA4922-1ARDZ-RL |
The ADA4922-1 is a differential driver for 16-bit to 18-bit 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.
