description

The TLC0820A, TLC0820B, ADC0820B, and ADC0820C are Advanced LinCMOS^TM

8-bit analog-to-digital converters each consisting of two 4-bit "flash" converters, a 4-bit digital-to-analog converter, a summing (error) amplifier, control logic, and a result latch circuit. The modified "flash" technique allows low-power integrated circuitry to complete an 8-bit conversion in 1.18 us over temperature. The on-chip track-and-hold circuit has a 100-ns sample window and allows these devices to convert continuous analog signals having slew rates of up to 100 mV/us without external sampling components. TTL-compatible 3-state output drivers and two modes of operation allow interfacing to a variety of microprocessors. Detailed information on interfacing to most popular microprocessors is readily available from the factory.

The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for operation from -40°C to 85°C. The M-suffix devices are characterized for operation over the full military temperature range of -55°C to 125°C. See Available Options.
