Straight Binary Transfer Function for Single-Ended, RANGE = 0 Single-Ended, RANGE = 1 Figure 44. Two’s Complement Transfer Function for Figure 45. Two’s Complement Transfer Function for Differential, RANGE = 0 Differential, RANGE = 1 Digital Inputs VDRIVE Functionality The AS1545 also has a VDRIVE feature to control the voltage at which the serial interface operates and allows the ADC to easily interface to both 3V and 5V processors. For example, if the AS1545 was operated with a VDD of 5V, the VDRIVE pin could be powered from a 3V supply, allowing a large dynamic range with low voltage digital processors. Therefore, the AS1545 could be used with the 2 × VREF input range, with a VDD of 5V while still being able to interface to 3V digital parts. 11...111 11...110 11....101 00...011 00...010 00...001 00...000 11...111 11...110 11....101 00...011 00...010 00...001 00...000 01 2 3 Input Voltage VINx (LSB) FS - 3/2LSB Full Scale = VREF Zero Scale = 0 1LSB = VREF/4096 0 1 2 3 Input Voltage VINx - VINy (LSB) FS - 3/2LSB Full Scale (FS) Transition Full Scale = +2VREF Zero Scale = 0 1LSB = VREF/4096 Full Scale (FS) Transition 011....111 011...110 000...010 000...001 000...000 111...111 111...110 111...101 100...001 100...000 -FS ZS Input Voltage VINx (LSB) +FS - 1LSB 011....111 011...110 000...010 000...001 000...000 111...111 111...110 111...101 100...001 100...000 -FS ZS Input Voltage VINx - VINy (LSB) +FS - 1LSB Full Scale = VREF/2 Zero Scale = -VREF/2 1LSB = VREF/4096 Full Scale = +VREF Zero Scale = -VREF 1LSB = VREF/4096 |
