AD7655-EP Enhanced Product Pin No. Mnemonic Type1 Description
35 CNVST DI Start Conversion. A falling edge on CNVST puts the internal sample-and-hold into the hold state and initiates a conversion. In impulse mode (IMPULSE = HIGH), if CNVST is held LOW when the acquisition phase (t8) is complete, the internal sample-and-hold is put into the hold state and a conversion is immediately started. 37 REF AI This input pin is used to provide a reference to the converter. 38 REFGND AI Reference Input Analog Ground. 39, 41 INB1, INB2 AI Channel B Analog Inputs. 40, 45 INBN, INAN AI Analog Inputs Ground Senses. Allow to sense each channel ground independently. 42, 43 REFB, REFA AI These inputs are the references applied to Channel A and Channel B, respectively. 44, 46 INA2, INA1 AI Channel A Analog Inputs. EPAD Exposed Pad. The exposed pad is connected to ground; however, this connection is not required to meet specified performance. 1 Al = input; DI = digital input; DO = digital output; DI/O = bidirectional digital; P = power.
