1. Functional Diagram

2. Description

The MLX90255BA linear sensor array consists

of a 128 x 1 array of photodiodes, associated

charge amplifier circuitry and a pixel data-hold

function that provides simultaneous-integration

start and stop times for all pixels. The pixels

measure 200µm (H) by 66 µm (W). Operation is

simplified by internal control logic that requires

only a serial-input (SI) signal and a clock.

Sample

The sensor consists of 128 photodiodes

arranged in a linear array. Light energy falling on

a photodiode generates photocurrent, which is

integrated by the active integration circuitry

associated with that pixel. During the integration

period, a sampling capacitor connects to the

output of the integrator through an analog

switch. The amount of charge accumulated at

each pixel is directly proportional to the light

intensity and the integration time. The output

and reset of the integrators is controlled by a

132-bit shift register and reset logic. An output

cycle is initiated by clocking in a logic 1 on SI.
