MAX12900 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE Ultra-Low-Power 4-20mA Sensor Transmitter General Description The MAX12900 is an ultra-low-power, highly integrated 4-20mA sensor transmitter. The MAX12900 integrates ten building blocks in a small package: a wide input supply voltage LDO, two conditioner circuits for pulse-widthmodulated (PWM) inputs, two low-power, low-drift, generalpurpose operational amplifiers (op amp) one wide bandwidth, zero-offset drift operational amplifier; two diagnostic parators, a power-up sequencer with power good output to allow for a smooth power-up, and a low-drift voltage reference. The MAX12900 converts PWM data from a microcontroller into current over a 4-20mA loop...
