General Description
AD9022 General Description
The AD9022 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. It 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 nearl 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 Samplifier™) can be used with the AD9022 to process signals up to and beyond 70 MHz.
