The AD7899 is a fast, low-power, 14-bit A/D converter that operates from a single 5 V supply. The part contains a 2.2 us successive-approximation ADC, a track/hold amplifier, 2.5 V reference, on-chip clock oscillator, signal conditioning circuitry,and a high-speed parallel interface. The part accepts analog input ranges of +-10 V, +- 5 V, +- 2.5 V, 0 V to 2.5 V, and 0 V to 5 V. Over voltage protection on the analog input for the part allows the input voltage to be exceeded without damaging the parts. Speed of conversion can be controlled either by an internally trimmed clock oscillator or by an external clock. A conversion start signal (CONVST) places the track/hold into hold mode and initiates conversion. The BUSY/EOC signal indicates the end of the conversion. Data is read from the part via a 14-bit parallel data bus using the standard CS and RD signals. Maximum throughput for the AD7899 is 400 kSPS. The AD7899 is available in a 28-lead SOIC and SSOP packages.
