ADM1063 VOLTAGE READBACK The ADM1063 has an on-board, 12-bit, accurate ADC for voltage readback over the SMBus. The ADC has a 13-channel analog mux on the front end. The 13 channels consist of the 10 SFD inputs (VH, VPx, and ...
Page 21
TEMPERATURE MEASUREMENT SYSTEM The ADM1063 contains an on-chip, band gap temperature sensor, whose output is digitized by the on-chip, 12-bit ADC. Theoretically, the temperature sensor and the ADC can measure temperatures from −128°C to +128°C with a resolution of 0.125°C. ...
Page 22
ADM1063 To measure ΔV , the sensor is switched between operating BE currents of I and N × I. The resulting waveform is passed through a 65 kHz low-pass filter to remove noise and through a chopper- stabilized amplifier that ...

POWER-UP (V > 2.5V) CC EEPROM UPDATING THE SEQUENCING ENGINE Sequencing engine (SE) functions are not updated in the same way as regular configuration latches. The SE has its own dedicated 512-byte nonvolatile, electrically erasable, programmable, read- only memory (EEPROM) ...
Page 26
ADM1063 The device also has several identification registers (read-only) that can be read across the SMBus. Table 12 lists these registers with their values and functions. Table 12. Identification Register Values and Functions Name Address Value Function MANID 0xF4 0x41 ...
