description

The TSL213 integrated opto sensor consists of 64 charge-mode pixels arranged in a 64

× 1 linear array. Each

pixel measures 120

µm × 70 µm with 125-µm center-to-center spacing. Operation is simplified by internal logic

requiring only clock and start-integration-pulse signals.

The TSL213 is intended for use in a wide variety of applications including linear and rotary encoding, linear

positioning, edge and mark detection, and contact imaging.

The TSL213 is supplied in an 8-pin dual-in-line clear plastic package.

Caution. These devices have limited built-in gate protection. The leads should be shorted together or the device placed in conductive

foam during storage or handling to prevent electrostatic damage to the MOS gates.
