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 APPLICATIONS Radar Receivers Digital Communications Digital Instrumentation Electro-Optics

The is a high speed, high performance, monolithic 12-bit analog-to-digital converter. All necessary functions, including track-and-hold (T/H) and reference, are included on-chip to provide a complete conversion solution. is a companion unit to the AD9023; the primary difference between the two is that all logic for the AD9022 is TTL-compatible, while the AD9023 utilizes ECL logic for digital inputs and outputs. Pinouts for the two parts are nearly identical. Operating from +5 V and ­5.2 V supplies, the AD9022 provides excellent dynamic performance. Sampling at 20 MSPS with AIN = 1 MHz, the spurious-free dynamic range (SFDR) is typically 76 dB; with AIN = 9.6 MHz, SFDR is 74 dB. SNR is typically 65 dB. The onboard T/H has a 110 MHz bandwidth and, more importantly, is designed to provide excellent dynamic performance for analog input frequencies above Nyquist. This feature is necessary in many undersampling signal processing applications, such as in direct IF-to-digital conversion. To maintain dynamic performance at higher IFs, monolithic RF track-and-holds (such as the AD9100 and AD9101 SamplifierTM) can be used with the AD9022 to process signals up to and beyond 70 MHz.

With DNL typically less than 0.5 LSB and 20 ns transient response settling time, the AD9022 provides excellent results when low-frequency analog inputs must be oversampled (such as CCD digitization). The full scale analog input 1 V with a 300 input impedance. The analog input can be driven directly from the signal source, or can be buffered by the AD96xx series of low noise, low distortion buffer amplifiers. All timing is internal to the AD9022; the clock signal initiates the conversion cycle. For best results, the encode command should contain as little jitter as possible. High speed layout practices must be followed to ensure optimum A/D performance. The AD9022 is built on a trench isolated bipolar process and utilizes an innovative multipass architecture (see the block diagram). The unit is packaged in 28-lead ceramic DIPs and gullwing surface mount packages. The AD9022 is specified to operate over the industrial to +85°C) and military to +125°C) temperature ranges.
