AD9260:  16-Bit High Speed Oversampled A/D Converter

Product Description

The AD9260 is a 16-bit, high speed oversampled analog-to-digital converter (ADC) that offers exceptional dynamic range over a wide bandwidth. The AD9260 is manufactured on an advanced CMOS process. High dynamic range is achieved with an oversampling ratio of 8X through the use of a proprietary technique which combines the advantages of sigma-delta and pipeline converter technologies.

The AD9260 is a switched-capacitor ADC with a nominal full-scale input range of 4V. It offers a differential input with 60dB of common mode rejection of common mode signals. The signal range of each differential input is +/- 1V centered on a 2.0V common -mode level.

The on-chip decimation filter is configured for maximum performance and flexibility. A series of three half-band FIR filter stages provide 8X decimation filtering with 85 dB of stopband attenuation and 0.004dB of passband ripple. An on-board digital multiplexer allows the user to access data from the various stages of the decimation filter. The on-chip programmable reference and reference buffer amplifier are configured for maximum accuracy and flexibility. An external reference can also be chosen to suit the users specific dc accuracy and drift requirements.

The AD9260 operates on a single +5V supply, typically consuming 550mW of power. A power scaling circuit is provided allowing the AD9260 to operate at power consumption levels as low as 150mW at reduced clock and data rates. The AD9260 is available in a 44-pin MQFP package and is specified to operate over the industrial temperature range.
