Description:
The DD-Series signal processing IC is designed to take an analog, sinusoidal input signal such as that
provided by NVE’s ABL-Series sensors and convert it to a two wire, current modulated digital output.
Inputs as small as 2 mV peak-to-peak can be provided to the IC, along with large signal offsets. The
DD001-12 part will provide a 50% duty cycle digital output signal.
The DD001-12 part contains a voltage regulator circuit, programmable amplifier, offset detection and
correction circuitry, and an EEPROM for setting gain and current levels. The voltage regulator output
(3.3V) is used to power the external sensor element, which should be connected between V
V
factory programmed to different levels for specific customer requirements.
Using the DD-Series signal processing IC allows the user to put the sensor element, which can very
small in a remote location, and pipe the signals from the sensor to the DD001-12 for digitizing
purposes. In addition, if two phase shifted sensor outputs are available (such as with the ABL014-00,
ABL015-00, and ABL015-00sensors), two DD001-12 parts can be used to provide two phase shifted
digital signals, for the purpose of detecting the direction of the gear tooth or encoder wheel.
The two-wire output of the DD001-12 can be easily converted to a three-wire current-sinking output
with the circuit shown in the GT Sensor applications section.
