DESCRIPTION
The ADS7807 is a low-power, 16-bit, sampling Analog-to-
Digital (A/D) converter using state-of-the-art CMOS struc-
tures. It contains a complete 16-bit, capacitor-based, Suc-
cessive Approximation Register (SAR) A/D converter with
sample-and-hold, clock, reference, and microprocessor inter-
face with parallel and serial output drivers.
The ADS7807 can acquire and convert 16-bits to within
±
1.5LSB 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 sys-
tems.
The ADS7807 is available in a 0.3" DIP-28 and SO-28, both
fully specified for operation over the industrial –40
°
C to
+85
°
C temperature range.
