ADC12020
12-Bit, 20 MSPS, 185 mW A/D Converter with Internal
Sample-and-Hold
General Description
The ADC12020 is a monolithic CMOS analog-to-digital con-
verter capable of converting analog input signals into 12-bit
digital words at 20 Megasamples per second (MSPS), mini-
mum. This converter uses a differential, pipeline architecture
with digital error correction and an on-chip sample-and-hold
circuit to minimize die size and power consumption while
providing excellent dynamic performance. Operating on a
single 5V power supply, this device consumes just 185 mW
at 20 MSPS, including the reference current. The Power
Down feature reduces power consumption to 40 mW.
The differential inputs provide a full scale input swing equal
to 2V
with the possibility of a single-ended input. Full use
of the differential input is recommended for optimum perfor-
mance. For ease of use, the buffered, high impedance,
single-ended reference input is converted on-chip to a differ-
ential reference for use by the processing circuitry. Output
data format is 12-bit offset binary.
This device is available in the 32-lead LQFP package and
will operate over the industrial temperature range of 40C to
+85C.
