DESCRIPTION
The ADC08B3000 is a single, low power, high
performance CMOS analog-to-digital converter that
digitizes signals to 8 bits resolution at sample rates
up to 3.4 Gigasamples Per Second, (Gsps).
Consuming a typical 1.6 Watts at 3 Gsps from a
single 1.9 Volt supply, this device is ensured to have
no missing codes over the full operating temperature
range. The unique folding and interpolating
architecture, the fully differential comparator design,
the innovative design of the internal sample-and-hold
amplifier and the calibration scheme enable an
excellent response of all dynamic parameters up to
Nyquist, producing a high 7.1 Effective Number Of
Bits, (ENOB), with a 748 MHz input signal and a 3
GHz sample rate while providing a 10^-18 Code Error
Rate. A sample rate of 3 Gsps is achieved by
interleaving two ADCs, each operating at 1.5 Gsps.
Output formatting is offset binary. The device
contains a 4K Capture Buffer with output on two 8-bit
Low Voltage CMOS (LVCMOS) output buses at rates
up to 200MHz.
The converter typically consumes less than 25 mW in
the Power Down Mode and is available in a 128-lead,
thermally enhanced exposed pad HLQFP and
operates over the Industrial (-40°C ≤ T_A ≤ +85°C)
temperature range.
