Description : Single Chip 12-Bit Data Acquisition System

DESCRIPTION
The LTC®1291 is a Data Acquisition System that contains a serial I/O successive approximation A/D converter. It uses LTCMOSTM switched capacitor technology to perform a 12-Bit unipolar A/D conversion. The input multiplexer can be configured for either single-ended or differential inputs. An on-chip sample-and-hold is included on the “+” input. When the LTC1291 is idle, it can be powered down in applications where low power consumption is desired. An external reference is not required because the LTC1291 takes its reference from the power supply (VCC). All these features are packaged in an 8-pin DIP.

FEATURES
■ Built-In Sample-and-Hold
■ Single Supply 5V Operation
■ Power Shutdown
■ Direct 3- or 4-Wire Interface to Most MPU Serial Ports and All MPU Parallel Ports
■ Two-Channel Analog Multiplexer
■ Analog Inputs Common Mode to Supply Rails
■ 8-Pin DIP Package

Description : 10-Bit Data Acquisition System for Autonomous Environmental Monitoring

INTRODUCTION
The SMD1102, SMD1103 and SMD1113 each contain a 10-Bit Data Acquisition System (DAS) with dedicated EEPROM alarm limit storage. The three devices communicate with the host µP via a standard two-wire I2C serial interface. After initialization the SMD1102/1103/1113 can automatically monitor one or more analog input channels. If any input Signal moves beyond its user-programmed limits the host is notified by the SMBALERT#output, enabling fault prediction in telecom line card applications, as an example.
