FEATURES DESCRIPTION
D Qualified for Automotive Applications The ADS5204 is a dual 10-bit, 40 MSPS analog-to-digital
D -V Single-Supply Operation converter (ADC). It simultaneously converts each analog
input signal into a 10-bit, binary coded digital word up to
D Dual Simultaneous Sample-and-Hold Inputs
a maximum sampling rate of 40 MSPS per channel. All
D Differential or Single-Ended Analog Inputs digital inputs and outputs are -V TTL/CMOS
D Programmable Gain Amplifier: 0 dB to 18 patible.
D Separate Serial Control Interface An innovative dual pipeline architecture implemented in
D Single or Dual Parallel Bus Output a CMOS process and the -V supply results in very
low power dissipation. In order to provide maximum

Low Power: 275 mW external references are available, the on-chip internal
D 300-MHz Analog Input Bandwidth references can be used. Both ADCs share mon
D -V TTL/patible Digital I/O reference to improve offset and gain matching. If
external reference voltage levels are available, the
