- 说明The DN1221 is a subminiature Bipolar Temperature
Controller for Thermoelectric Coolers (TEC) used in fixed
temperature OEM applications. The device is designed to
operate with a negative temperature coefficient (NTC)
thermistor that senses the temperature of the object
attached to the TEC. Temperature is set with a user
ed resistor. Temperature stability of 0.01°C is
achieved by the linear PI control loop of the DN1221.
Proportional gainintegrator time constant are set
independently with resistors. No external integrator
capacitor is needed. These parameters can be optimized to
minimize temperature overshootstability. In addition,
the maximum coolingheating current supplied to the
TEC can be adjusted independently from 0 to 2.2 amperes
with two resistors.
An evaluation kit is available that contains the DN1221, a
fan cooled TEC,an aluminum cold plate (with
imbedded thermistor) that is attached to the TEC. The
evaluation kit operates on a 12 VDC power supply.
Temperature of the cold plate can be changed from 0 to 60
°C with a variable resistor. The TEC is mounted on a
socket so that it can be easily removed.

- 说明The DN135 is a current to voltage converter that is intended for use in
fiber optic power monitors. The device converts current from a
photodiode to voltage that is proportional to the incoming optical power in
dBm. The DN135 functions equally well with InGaAsSilicon
photodiodes.
70dB DYNAMIC RANGE
CONVERTS CURRENT LEVELS FROM 100pA to 2mA
0.500 VOLTS OUTPUT PER DECADE INCREASE IN OPTICAL POWER
OPERATES FROM ± 5 VOLTS SUPPLIES

- 说明The DN1410 is a pigtailed fiberoptic power monitor using an
InGaAs photodiode detector. This device provides an output
voltage that is proportional to the incoming optical power in
dBmis capable of measuring optical power from -70dBm to
+0dBm at a wavelength of 1550nm. The DN1410 is ideally
suited for monitoring optical power in fiber optic communication
systems.
