v01.0411
Dual 13/12-Bit 20/40 MSPS
a/D Converter
Features
• 13-bit resolution
• 20/40 MsPs Maximum sampling rate
• Ultra-Low Power Dissipation: 30/55 mW
• 72.5 dB snr @ 8 MHz FIn
• Internal reference Circuitry
• 1.8 v Core supply voltage
• 1.7 - 3.6 v I/o supply voltage
• Parallel CMos output
• 9 x 9 mm 64-Pin QFn (LP9e) Package
General Description
the HMCAD1050-40 is a high performance low
power dual analog-to-digital converter (ADC). the
ADC employs internal reference circuitry, a CMos
control interface, CMos output data and is based
on a proprietary structure. Digital error correction is
employed to ensure no missing codes in the complete
full scale range.
several idle modes with fast startup times exist. each
channel can be independently powered down and
the entire chip can either be put in standby Mode or
Power Down mode. the different modes are optimized
to allow the user to select the mode resulting in the
lowest possible energy consumption during idle mode
and startup.
the HMCAD1050-40 has a highly linear tHA optimized
for frequencies up to 70 MHz. the differential clock
interface is optimized for low jitter clock sources and
supports LvDs, LvPeCL, sine wave and CMos clock
inputs.
Pin compatible with HMCAD1040-40, HMCAD1040-80
and HMCAD1050-80.
