OPRODUCT DESCRIPTION
BThe AD9022 is a high speed, high performance, monolithic 12- bit analog-to-digital converter. All necessary functions, includ-
Sing track-and-hold (T/H) and reference, are included on chip to Oprovide a plete conversion solution. It is a panion unit to the AD9023; the primary difference between the two is that
Lall logic for the AD9022 is TTL patible, while the AD9023 utilizes ECL logic for digital inputs and outputs. Pinouts for the
Etwo parts are nearly identical. TEOperating from +5 V and
