| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MMAS40G10D/D Micromachined Accelerometer 40g The MMAS40G family of silicon capacitive, micro-machined accelerometers features integral signal amplification, signal conditioning, a 4-pole low-pass filter and temperature compensation. Zero-G offset, full scale span and filter roll-off are factory set and require no external passives. A calibrated self-test feature mechanically displaces the seismic mass with the application of a digital self-test signal. The MMAS40G incorporates a single polysilicon seismic mass, suspended between two fixed polysilicon plates (G-cell). The forces of acceleration move the seismic mass, thereby resulting in a change in capacitance. The G-cell is sealed at the wafer level, creating a particle-free environment. The G-cell features built-in damping and over-range stops to protect it from mechanical shock. MMAS40G accelerometers are ideally suited for automotive crash detection and recording, vibration monitoring, automotive suspension control, appliance control systems, etc. Features * Minimum Full Scale Measurement 40g * Calibrated, True Self-Test * Standard 16-Pin Plastic DIP package * Senses Perpendicular to the Printed Circuit Board * Integral Signal Conditioning and 4-Pole Filter * Linear Output * Robust, High Shock Survivability 1 2 3 4 5 6 MMAS40G10D MICROMACHINED ACCELEROMETER 40g 10 9 12 11 14 13 16 15 78 56 34 12 DIP PACKAGE CASE 648C-03 PIN NUMBER (DIP) N/C (1) N/C (1) N/C (1) Self-Test Output Bypass (2) GND VS (2) 9 10 11 12 13 14 15 16 N/C (1) N/C (1) N/C (1) N/C (1) N/C (1) N/C (1) N/C (1) N/C (1) SIMPLIFIED BLOCK DIAGRAM + + 8 + VS 7 8 4 SELF-TEST g G-CELL A 6 BYPASS NOTES: 1.

The output voltage increases from the Zero Acceleration Output for positive acceleration and decreases for negative acceleration. The typical sensitivity is 40 mV/g. For example, with VS = 5.0 V, a + 20g input will result in a 3.3 V output. (Voutput = 2.5 + 0.040 x 20) and a - 20g input will result in a 1.7 V output. 2. Sensitivity is a ratiometric parameter: V/G(Vs) = V/G(5 V) x (VS / 5 V). 3. The compensated temperature operating range is - 40 to +85C. 4. Zero Acceleration Output is a ratiometric parameter: Voff(Vs) = Voff(5 V) x (VS / 5 V). 5. Equivalent output in response to a Logic Level One on the self-test pin. 6. Additional temperature range available. Consult factory.
