SM3322ARA
Optical Sensor IC
OVERVIEW
The SM3322ARA is a fluorescence detector IC with a built-in single picture element (pixel) photodiode of 1mm2 and programmable
signal conditioning circuit. The IC has an optical filter on chip with target condition 640nm ± 60nm, and it integrates all the elements
required for optical sensor into an ultra-miniature package. The signal condition circuit has a programmable gain amplifier with dark
current compensation circuit, so that it can operate in wider temperature range. With 3 addressing bits, up to 8 SM3322ARA can be
paralleled.

SM3322ARA
FUNCTIONAL DESCRIPTION
Basic Function
The SM3322ARAdetects the current generated from a photodiode and outputs a voltage signal.
The transimpedance of the preamplifier can be adjusted for coarse adjustment of the responsivity. The transimpedance adjustment range
is 0.5 to 60M, set using 4 adjustment bits. Also, a dark current compensation circuit is used to compensate photodiode output under dark
lighting conditions for output voltage stability with low temperature variation.
The gain of the postamplifier can be adjusted for fine adjustment of the responsivity. The gain adjustment range is 1 to 4 times, set using 4
adjustment bits.Also, a built-in offset cancel circuit is used to provide low offset voltage at the output.
The output voltage when there is no photoirradiation, called the dark voltage, is 0.1VDD. The maximum output voltage with
photoirradiation is 0.7VDD.
The device can be addressed using address pin control. This function allows the transimpedance and gain settings to be adjusted for each
device independently when multiple devices are connected in parallel.An output enable control (OE) is used for output control.

Serial Interface
The SM3322ARA use a 3-wire serial interface (SE, CLK, DATA) to access the device and to set an internal register to control device
operation. Note that extraneous signal input on the serial interface pins must be avoided when not reading/writing data to the device to
prevent incorrect operation.
Internal Register Structure
The device read/write mode, address, operating mode, preamplifier transimpedance, and postamplifier gain are set in an internal register.
The device can be accessed for writing data to or reading data from the register when the A[2:0] address write data bits match the setting
of the address control inputs (A2 toA0).
Note that register data must be configured before using the device.
