描述 Description

The ADC08B200 is a high speed analog-to-digital converter (ADC) with an integrated capture buffer. The 8-bit, 200 MSPS A/D core is based upon the proven ADC08200 with integrated track-and-hold and is optimized for low power consumption. This device contains a selectable size capture buffer of up to 1,024 bytes that allows fast capture of an input signal with a slower readout rate. An on-chip clock PLL circuit provides the option of on-chip clock rate multiplication to provide the high speed sampling clock.The ADC08B200 is resistant to latch-up and the outputs are short-circuit proof. The top and bottom of the ADC08B200's reference ladder are available for connections, enabling a wide range of input possibilities. The digital outputs are TTL/CMOS compatible with a separate output power supply pin to support interfacing with 2.7V to 3.3V logic. The digital inputs and outputs are low voltage TTL/CMOS compatible and the output data format is straight binary.The ADC08B200Q runs on an Automotive Grade Flow and is AEC-Q100 Grade 2 Qualified. The ADC08B200 is offered in a 48-pin plastic package (TQFP) and is specified over the extended industrial temperature range of ?40°C to +105°C. An evaluation board is available to assist in the easy evaluation of the ADC08B200.
