The ADM1185 is an integrated, 4-channel, voltage monitoring and sequencing device. A 2.7 V to 5.5 V power supply is required on the VCC pin to power the device.
Four precision comparators monitor four voltage rails. All comparators have a 0.6 V reference with a worst-case accuracy of 0.8%. Resistor networks that are external to the VIN1, VIN2, VIN3, and VIN4 pins set the trip points for the monitored supply rails.
A digital core interprets the status of the comparator outputs.
Internal time delays can be used for sequencing the startup of subsequent power supplies enabled by the outputs. Supplies falling out of range are also detected and, as a result, appropriate outputs are disabled.
The ADM1185 has four open-drain outputs. In a typical configuration, OUT1 to OUT3 are used to enable power supplies, while PWRGD is a common power-good output, indicating the status of all monitored supplies.
The ADM1185 is available in a 10-lead mini small outline package (MSOP).

Evaluation Kits 4
EVAL-AD7768
AD7768 Evaluation Board
Product Detail
The AD7768 evaluation software fully configures the AD7768 device register functionality and provides dc and ac time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.
The EVAL-AD7768FMCZ is an evaluation board that allows the user to evaluate the features of the ADC. The user PC software executable controls the AD7768 over a USB cable through the EVAL-SDP-CH1Z System Demonstration Platform (SDP). The AD7768 evaluation software requires PC running Windows® 7 to Windows 10 with a USB 2.0 port.
Full specifications on the AD7768 are available in the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.
