TI has developed an improved version of the industry standard ADC083x family of 8 bit Analog to Digital Converters. These replacements have been upgraded to allow a faster conversion clock. Previous versions of this family support a conversion clock up to 400 KHz, but the new TLC083x family is specified up to 600 KHz. This reduces conversion time to 13 µs minimum, a 50% reduction over comparable versions.
The TLC083x family is available in 1, 2, 4 or 8 input versions
as designated by the last digit of the device number. The 2, 4
or 8 input versions are software configurable for single-ended
or differential inputs. All versions are specified to have total
unadjusted error of ±1 LSB and require no full scale or zero
error adjustments. These ADCs are easily interfaced to microcontrollers
and microprocessors using a serial output data format. The serial
data output is ideal for remote sensing applications using a digital
data link. The digital I/O pins are TTL and CMOS compatible. Fabricated
in a CMOS process, only 5 V is required to operate and draws only
1 mA typical (2.5 mA max). The ADC can be operated ratiometrically
using VCC or can be fixed to a 5 V precision reference. This family
of devices is available in the surface mount (SOIC) and standard
(DIP) packages.
