The DS1856M dual, temperature-controlled, nonvolatile (NV) variable resistors with three monitors consists of two 256-position, linear, variable resistors; three analog monitor inputs (MON1, MON2, MON3); and a direct-to-digital temperature sensor. The device provides an ideal method for setting and temperature-compensating bias voltages and currents in control applications using minimal circuitry. The variable resistor settings are stored in EEPROM memory and can be accessed over the 2-wire serial bus.
The DS1856M includes 128 bytes of EEPROM memory at A2h slave address, Table 00/01. The DS1856M also includes three-levels of password protection. The DS1856-01 includes 256 bytes of A0h EEPROM memory. The DS1856B-M50+ and DS1856E-M50+ are drop-in replacements for the DS1856B-050+ and DS1866E-050+, respectively. The enhancements include 256 bytes of EEPROM at A0h; selectable MON2, MON3 references; and a 13-bit ADC. These are backward compatible by default with the DS1856B-050+/DS1856E-050+.
