Description : 10-Bit DATA ACQUISITION System for Autonomous Environmental Monitoring View

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.

Part Name(s) : TC835CBU TC835CKW TC835CPI TC835 TelCom-Semiconductor
TelCom Semiconductor Inc => Microchip
Description : PERSONAL COMPUTER DATA ACQUISITION A/D CONVERTER View

GENERAL DESCRIPTION
The TC835 is a low-power, 4-1/2 digit (0.005% resolution), BCD analog-to-digital converter (ADC) that has been characterized for 200 kHz clock rate operation. The five conversions per second rate is nearly twice as fast as the ICL7135 or TC7135. The TC835 (like the TC7135) does not use the external diode-resistor roll-over error compensation circuits required by the ICL7135.
The multiplexed BCD DATA output is perfect for interfacing to personal computers. The low-cost, greater than 14-bit high-resolution, and 100 µV sensitivity makes the TC835 exceptionally cost-effective.
Microprocessor-based DATA ACQUISITION systems are supported by the BUSY and STROBE outputs, along with the RUN/HOLD input of the TC835. The overrange, under range, busy, and run/hold control functions and multiplexed BCD DATA outputs make the TC835 the ideal converter for µP-based scales and measurement systems and intelligent panel meters.*
The TC835 interfaces with full-function LCD and LED display decoder/drivers. The UNDERRANGE and OVERRANGE outputs may be used to implement an autoranging scheme or special display functions.

FEATURES
■ Upgrade of Pin-Compatible TC7135, ICL7135, MAX7135 and SI7135
■ Guaranteed 200 kHz Operation
■ Single 5V Operation With TC7660
■ Multiplexed BCD DATA Output
■ UART and Microprocessor Interface
■ Control Outputs for Auto-Ranging
■ Input Sensitivity ............................................ 100 µV
■ No Sample and Hold Required

APPLICATIONS
■ Personal Computer DATA ACQUISITION
■ Scales, Panel Meters, Process Controls
■ HP-IL Bus Instrumentation
