AD9022

a 12-Bit 20 MSPS Monolithic A/D Converter AD9022 FEATURES Monolithic 12-Bit 20 MSPS A/D Converter Low Power Dissipation: 1.4 Watts On-Chip T/H and Reference High Spurious-Free Dynamic Range TTL Logic FUNCTIONAL BLOCK DIAGRAM ANALOG INPUT T/H 5-BIT ADC DAC 5-BIT ADC DIGITAL ERROR 12 CORRECTION TTL APPLICATIONS Radar Receivers ENCODE T/H 16 DAC Digital Communications Digital Instrumentation Electro-Optics +2V REF 8 4-BIT ADC +5V –5.2V GND 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 complete conversion solution. It is a companion unit to the AD9023; the primary difference between the two is that Lall logic for the AD9022 is TTL compatible, while the AD9023 utilizes ECL logic for digital inputs and outputs. Pinouts for the Etwo parts are nearly identical. TEOperating from +5 V and –5.2 V ...
