General Description
nꢀ
10-bit resolution
The CDK1308 is a high performance ultra low power analog-to-digital
converter (ADC). The ADC employs internal reference circuitry, a CMOS
control interface and 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.

Internal reference circuitry
1.8V core supply voltage
1.7 – 3.6V I/O supply voltage
Parallel CMOS output
Two idle modes with fast startup times exist. The entire chip can either be
put in Standby Mode or Power Down mode. The two modes are optimized to
allow the user to select the mode resulting in the smallest possible energy
consumption during idle mode and startup.
40-pin QFN package
Pin compatible with CDK1307
The CDK1308 has a highly linear THA optimized for frequencies up to Nyquist.
The differential clock interface is optimized for low jitter clock sources and
supports LVDS, LVPECL, sine wave, and CMOS clock inputs.
