Preliminary specification
Trigger amplifier with two wire current interface
UZZ7000T
FUNCTIONAL DESCRIPTION
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 circuitry includes a voltage regulator for supply to an
external sensor bridge.
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 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.
