SLA64 (Preliminary)

Features

A 1 x 64 element silicon-based thermopile array. Each active area is 0.45mm x 2.0mm with a time constant of 42ms and a low Temperature Coefficient of Responsivity of -0.06%/°C. It is packaged in a 68-pin QIP. Includes internal 30kΩ 5% NTC chip thermistor provides ambient package temperature measurement. See Thermistor Options p/n: MT04.
