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 ±

2.0g 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.

ical of vibration) or dc accelerations, (such as inertial force or constant, gravity-induced accelerations).

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: S IN X (T IN ) 2.67 = S FIN X (T FIN ) 2.67 (Temperature in °K) See Application Note

(AN-00MX-001).
