Low-Power 12-Bit Sampling CMOS
ANALOG-to-DIGITAL CONVERTER
DESCRIPTION
The ADS7806 is a low-power 12-bit sampling analog-
to-digital using state-of-the-art CMOS structures. It
contains a complete 12-bit, capacitor-based, SAR A/D
with S/H, clock, reference, and microprocessor inter-
face with parallel and serial output drivers.
The ADS7806 can acquire and convert to full 12-bit
accuracy in 25
μ
s max while consuming only 35mW
max. Laser-trimmed scaling resistors provide standard
industrial input ranges of
±
10V and 0V to +5V. In
addition, a 0V to +4V range allows development of
complete single supply systems.
The 28-pin ADS7806 is available in a plastic 0.3" DIP
and in an SOIC, both fully specified for operation over
the industrial –40
°
C to +85
°
C temperature range.
