- 备注：
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.

DN405–RTD
- 品牌：
THERMOPTICS
- 封装：
DIP
- 数量：
100
- 备注：
The DN405 is a four wire 100 ohm platinum resistance temperature detector (RTD) signal conditioning circuit that transforms RTD resistance to a voltage that is proportional to temperature in °C. This device was designed to operate with a 100 ohm IEC/DIN-grade Platinum RTD that exhibits an alpha value of 0.00385!/!/°C. Analog circuit linearization provides typical accuracy of ±0.5°C over a temperature range of -100°C to +400°C. The four wire measurement circuit eliminates the effect of lead resistance that allows the RTD to be remotely located from the DN405 signal conditioning circuit. The DN405, which operates from a single supply voltage of +2.7V to +5.5V, draws only 1.3mA of current, making it ideal for portable applications. The DN405 compensates for the inherent non-linearity of all platinum RTDs. The output voltage of the device is directly proportional to the temperature of the RTD. No digital signal processing is required to make accurate temperature measurements. The four wire capability of the DN405 makes it possible to multiplex several RTDs with one device. This is useful in data
