Overview
The AD9200JRSZ is a high-performance, 10-bit, 20 MSPS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This monolithic, single-supply ADC features an on-chip sample-and-hold amplifier and voltage reference, making it suitable for a variety of high-speed applications. The AD9200JRSZ is designed to operate within a supply range of 2.7 V to 5.5 V, making it ideal for low-power, high-speed portable applications. It is available in a 28-lead SSOP package and is pin-compatible with the AD876, facilitating easy migration from older designs to lower supply voltages.
