It is equipped with a two wire current interface. The polarity  
of an input voltage difference triggers the circuit supply  
current between 7 and 14 mA.  
The device also includes a voltage regulator for supply to  
an external sensor bridge.

Preliminary specification  
Trigger amplifier with two wire current interface  
UZZ7000T  
FUNCTIONAL DESCRIPTION  
An on-chip temperature sensor adapts the comparator  
hysteresis to the temperature dependent sensitivity of a  
typical magnetoresistive sensor from the Philips  
MR-Sensor KMZ families.  
The UZZ7000 is a differential input trigger amplifier with a  
two wire interface and sensor supply regulator. It is  
designed for application with magnetoresistive sensor  
bridges. The block diagram is shown in Fig.4  
The UZZ7000T device and the connected sensor bridge  
are supplied from a two wire current interface. The digital  
output is directly related to the differential voltage input  
between pins SA and SB which switches the constant  
current source between 7 and 14 mA.  
The circuitry includes a voltage regulator for supply to an  
external sensor bridge.
