KX220-1072

**PART NUMBER: ± 40g Tri-axis Analog KX220-1072 Accelerometer Specifications Rev. 1.0 31-Oct-2017** 

## **Product Description** 

The KX220-1072 is a Tri-axis, silicon micromachined accelerometer with a full-scale output range of ±40g (392 m/s/s). The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further utilizes common mode cancellation to decrease errors from a? process variation, temperature, and environmental stress. The sense element is hermetically sealed at the wafer level by bonding a second silicon lid wafer to the device using a glass frit. A separate ASIC device packaged with the sense element provides signal conditioning and self-test. The accelerometer is delivered in a 3 x ey 3 x 0.9 mm Land Grid Array (LGA) plastic package operating from a 1.8V – 3.6V DC supply. The KX220 features an internal low pass filter that can be disabled or factory programmed to 50Hz, 100Hz, 500Hz, 1kHz, or 2kHz. 

There are 2 factory programmable modes of operation for the KX220: 

**Mode 00** – The Enable pin must be **HIGH** for normal operation and **LOW** for power shutdown. 

**Mode 01** – The Enable pin must be **LOW** for normal operation and **HIGH** for power shutdown. 

The KX220-1072 is factory programmed to be in MODE 00 with no low pass filter 

## **Features** 

- 3 x 3 x 0.9 mm LGA 

- Wide signal bandwidth 

- Factory-programmable internal low-pass filter (50Hz, 100Hz, 500Hz, 1kHz, 2kHz, no LPF) 

- Analog outputs 

- Good temperature performance 

- Low current consumption: 5 µA in standby, 240 µA at full power 

- Self-test function

1. Power up time is determined by 5 times the RC time constant of the factory programmed or user defined low pass filter. 

2. Factory programmable to either have _no low pass_ filter or have a switched capacitor low pass filter with cutoff frequency (-3dB) at _2kHz_ , _1kHz_ , _500Hz_ , _100Hz_ , or _50Hz_ . Optionally, the user can lower the bandwidth with external capacitors connected to output pins 6, 7, and 8. Note, maximum is defined by the frequency response of the sensor itself (see Table 1 for details).

**PART NUMBER: ± 40g Tri-axis Analog KX220-1072 Accelerometer Specifications Rev. 1.0 31-Oct-2017** ~~Kf~~ **Power-On Procedure** Proper functioning of power-on reset (POR) is dependent on the specific **VDD, VDDLOW** , **TVDD** (rise time) **,** and **TVDD_OFF** profile of individual applications. It is recommended to minimize **VDDLOW,** and **TVDD** , and maximize **TVDD_OFF** . It is also advised that the **VDD** ramp up time **TVDD** be monotonic. Note that the outputs will not be stable until **VDD** has reached its final value. 

_To assure proper POR, the application should be evaluated over the customer specified range of VDD, VDDLOW, TVDD, TVDD_OFF and temperature as POR performance can vary depending on these parameters._ 

Please refer to Technical Note _**TN002 Power-On Procedure**_ for more information.

## **Application Design Equations** 

The bandwidth is determined by a factory programmable switched capacitor filter. The filter can be set at the factory to be 2kHz, 1kHz, 500Hz, 100Hz, 50Hz, or no low pass filter. Alternatively, bandwidth can be reduced by addition of a capacitor on the output pins 5, 6, and 7 according to the equation:
