PRODUCTION DATA SHEET

KEY FEATURES

DESCRIPTION

Near Human Eye Spectral

Response

The LX1974 is a low cost silicon

light sensor with spectral response that resistors (typically in the range of 10K

closely emulates the human eye. to 100K) and power supply values.

Patented circuitry produces peak Typically the LX1974 needs only 1.8V

spectral response at 520nm, with IR of headroom to operate at 1000 Lux

response less than ±5%, of the peak illumination.

Dynamic range is determined by the

response, above 900nm.

Internal temperature compensation

The photo sensor is a PIN diode array allows dark current to be kept below

with a linear, accurate, and very 200nA over the full specification

repeatable current transfer function. temperature range (-40 to +85°C),

High gain current mirrors on the chip providing high accuracy at low light
