Product details

Description

Sense pin (to Rs1+ Cs1) Sense pin (to Cs1 electrode) Do not connect Speed option Do not connect Output, key 1 Output, key 2 Ground Sync in and/or spread spectrum drive Unbonded internally Unbonded internally Do not connect Reset pin, active low.

Features

spread-spectrum acquisition capability, external synchronization of acquire bursts, and fast and slow acquisition modes. These modes are enabled via high-value resistors connected to the SNS pins to ground or Vdd. These resistors are required in every circuit. There are two basic modes as shown in Figures 1-1 and 1-2. Low-power Sync mode: In this mode the device operates with about a 100ms response time and very low current (about 90µA average at 4.0V). This mode allows the device to be synchron.
