Analog Devices AD7729 Datasheet
The AD7729 is a monolithic 3 V CMOS dual sigma‑delta ADC that provides two 15‑bit channels (I and Q) with on‑chip digital filtering and an auxiliary 10‑bit DAC for functions such as automatic gain control. It is supplied in 28‑lead TSSOP or SOIC packages and is intended for applications like GSM base stations and pagers.
Key specifications include a 13 MSPS input sample rate, 270.83 kHz output word rate, 2.7–3.3 V supply range, and an operating temperature range of –40 °C to +105 °C. Detailed pin configurations, timing diagrams, and register maps are provided for system integration.
