MAXIM INTEGRATED / ANALOG DEVICES ICL7109EPL+ Datasheet & Stock

The ICL7109EPL+ from Maxim Integrated Products is a 12bit analogue to digital converter (ADC) with 3-state binary outputs in 40 pin DIP package. This is a monolithic converter designed for easy interface with microprocessors and URATs. The 12bit binary plus polarity and over range outputs can be directly interfaced to a microprocessor bus. In this mode, IC is controlled by the microprocessor through chip select and two byte enable inputs. For remote data logging applications, IC outputs are easily converted to a UART handshake mode. This device offers high accuracy by lowering rollover error to less than 1 count and zero reading drift to less than 1µV/°C. It is used in wide range of data acquisition and control applications which involve the measurement of analogue data such as pressure, speed, voltage, resistance, flow, weight, temperature, power and current.
