FEATURES
DESCRIPTION
Operating from a single 5V power supply, the
2
• 8-Channel Programmable Differential or
ADC12048 is a 12 bit + sign, parallel I/O, self-
Single-Ended Multiplexer
calibrating, sampling analog-to-digital converter
• Programmable Acquisition Times and User-
(ADC) with an eight input fully differential analog
Controllable Throughput Rates
multiplexer. The maximum sampling rate is 216 kHz.
On request, the ADC goes through a self-calibration
• Programmable Data Bus Width (8/13 bits)
process that adjusts linearity, zero and full-scale
• Built-in Sample-and-Hold
errors.
• Programmable Auto-Calibration and Auto-Zero
The ADC12048's 8-channel multiplexer is software
cycles
programmable to operate in a variety of combinations
• Low Power Standby Mode
of single-ended, differential, or pseudo-differential
• No Missing Codes
modes. The fully differential MUX and the 12-bit +
sign ADC allows for the difference between two
signals to be digitized.
APPLICATIONS
• Medical Instrumentation
The ADC12048 can be configured to work with many
popular microprocessors/microcontrollers and DSPs
• Process Control Systems
including Tl's HPC family, Intel386 and 8051,
• Test Equipment
TMS320C25, Motorola MC68HC11/16, Hitachi 64180
• Data Logging
and Analog Devices ADSP21xx.
• Inertial Guidance
For complementary voltage references see the
LM4040, LM4041 or LM9140.
