DescriptionThe ADC12048CIV is one member of the ADC12048 family which is designed as the 12-bit plus sign 216 kHz sampling analog-to-digital converter that can be used in (1)medical instrumentation; (2)process control systems; (3)test equipment; (4)data logging; (5)inertial guidance. Also this device can be configured to work with many popular microprocessors/microcontrollers including National's HPC family, Intel386 and 8051, TMS320C25, Motorola MC68HC11/16, Hitachi 64180 and Analog Devices ADSP21xx.
Features of the ADC12048CIV are:(1)fully differential analog input; (2)programmable acquisition times and user-controllable throughput rates; (3)programm-able data bus width (8/13 bits); (4)built-in sample-and-hold; (5)programmable auto-calibration and auto-zero cycles; (6)low power standby mode; (7)no missing codes. And the key specifications of this device are:(1)resolution 12-bits + sign; (2)13-bit conversion time 3.6 s, max; (3)13-bit throughput rate 216 ksamples/s, min; (4)integral linearity error (ILE) ±1 LSB, max; (5)single supply +5V ± 10%; (6)VIN range GND to VA+.
The absolute maximum ratings of the ADC12048CIV can be summarized as:(1)supply voltage (VA+ and VD+):6.0 V;(2)voltage at all inputs:-0.3V to V+ + 0.3V;(3)|VA+ to VD+|:300 mV;(4)|AGND - DGND|:300 mV;(5)input current at any pin:±30 mA;(6)package input current:±120 mA;(7)power dissipation at TA=25°C:500 mW;(8)storage temperature:-65°C to +150°C;(9)ESD susceptibility:3.0 kV.
