The MXD202 is a very low cost dual-axis acceleration sensor on a monolithic IC. With no moving parts,
the device is extremely reliable and is manufactured on a submicron CMOS process enabling small
geometries and small die size, resulting in low overall cost and high functionality. The MXD202 is pri-
marily designed for applications requiring high performance and where overall system cost is a driving
factor in component selection. The MXD202 measures acceleration with a full-scale range of up to ±
2.0
g
and produces a PWM digital signal output. Sensor is shipped with a duty cycle period of 10 milli-
Seconds (100 Hz). Special order sensors are available with a duty cycle period of 2.5 milli-Seconds
(400 Hz).Typical noise floor is .01% Duty Cycle
Hz, allowing signals below 1.0 milli-
g
to be resolved.
Frequency response extends to 40 Hz. The frequency response can be extended to 160 Hz with the
implementation of a simple external circuit.
The MXD202 is a dc accelerometer with the capability to measure both ac acceleration, (typ-
ical of vibration) or dc accelerations, (such as inertial force or constant, gravity-induced accelerations).
The MXD202 offers digital output signals which duty cycles (ratio of pulse width to period)
are proportional to the acceleration in each of the axes of sensitivity. The outputs can be measured
directly with a microprocessor counter, eliminating the need for A/D converter or glue logic. The output
duty cycle is programmable over a wide range of sensitivity. MXD202 offers a calibrated temperature
sensor output with a positive temperature coefficient of 5.0 mV/°C. This device can be temperature
compensated easily. The change in sensitivity over the temperature range –40°C to 125°C is pre-
dictable and follows the physical gas laws. The following equation can be used to predict the sensitivi-
ty at any given temperature:
SINX (TIN)2.67= SFINX (TFIN)2.67
(Temperature in
°
K) See Application Note
(AN-00MX-001).
The MXD202 is available in a metal can (TO-100) or a surface mount (LCC);both are her-
metic and are specified over the temperature range -40
°
C to 125
°
C.
