MX171
AMPLITUDE TYPE AUTO FOCUS IC
FEATURES
• Package : 8-pin SOP, 8-pin DIP
• Operating voltage : 2.2V~6V
• Operating temperature : -25oC~60oC
• Surround light level : max. 20uA (SPD output current)
• IRED drive output : min. 15mA

DESCRIPTION
MX171 is designed for Amplitude system auto focus
cameras. It is regarded as input component for SPD
(Silicon Photo Detector), and comprises of circuits that
drive AF magnet as output, an infrared emission diode
current control circuit, and control circuit of sequential
timing.
