SBAS301D October 2003 – February 2020 ADS1204
PRODUCTION DATA.
The supplies can be sequenced in any order, but in no case must any analog or digital input exceed the respective analog or digital power-supply voltage and current limits. In particular, inputs to the ADS1204, such as CH x+, CH x–, and CLKIN, should not be present before the power supply is on. Violating this condition could cause latch-up. If these signals are present before the supply is on, series resistors should be used to limit the input current to a maximum of 10 mA.
Wait approximately 600 µs after all power supplies are stabilized before communicating with the device to allow the power-on reset process to complete.
