Functional Description

The ADC08351 achieves 6.8 effective bits at 21 MHz input

frequency with 42 MHz clock frequency digitizing to eight bits

the analog signal at V

IN that is within the nominal voltage

range of 0.5 V

P-P to 0.68 VA.

Input voltages below 0.0665 times the reference voltage will

cause the output word to consist of all zeroes, while input

voltages above 3⁄4 of the reference voltage will cause the

output word to consist of all ones. For example, with a V

REF

of 2.4V, input voltages below 160 mV will result in an output

word of all zeroes, while input voltages above 1.79V will

result in an output word of all ones.

The output word rate is the same as the clock frequency.

Data is acquired at the falling edge of the clock and the

digital equivalent of that data is available at the digital out-

puts 2.5 clock cycles plus t

OD later. The ADC08351 will

convert as long as the clock signal is present at the CLK pin,

but the data will not appear at the outputs unless the OE pin

is low. The digital outputs are in the high impedance state

when the OE pin or when the PD pin is high.

Applications Information (All schematic

pin numbers refer to the TSSOP.)

1.0 THE ADC REFERENCE AND THE ANALOG INPUT

The capacitance seen at the input changes with the clock

level, appearing as 4 pF when the clock is low, and 11 pF

when the clock is high. Since a dynamic capacitance is more

difficult to drive than is a fixed capacitance, choose an

amplifier that can drive this type of load. The CLC409,
