PRODUCTION DATA
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
INPUT or REFERENCE | |||
INAP | 10 | I | Positive analog input, channel A |
INAM | 11 | I | Negative analog input, channel A |
INBP/NC | 14 | I | Positive analog input, channel B (NC on single channel device) |
INBM/NC | 15 | I | Negative analog input, channel B (NC on single channel device) |
VREF | 17 | I | 1.2V external voltage reference input. A 10μF and a 0.1μF ceramic bypass capacitor connected between VREF and GND pins and placed as close to the pins as possible is recommended when using external reference. Otherwise, connect to GND when using internal reference. |
VCM | 7 | O | Common-mode voltage output to provide DC bias for the analog inputs, 1.25V |
CLOCK | |||
CLK | 8 | I | Sampling clock input for the ADC |
