1 / 17 page TLC0820AC, TLC0820AI Advanced LinCMOS ™ HIGH-SPEED 8-BIT ANALOG-TO-DIGITAL CONVERTERS USING MODIFIED FLASH TECHNIQUES SLAS064A – SEPTEMBER 1986 – REVISED JUNE 1994 2–1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Advanced LinCMOS™ Silicon-Gate Technology D 8-Bit Resolution D Differential Reference Inputs D Parallel Microprocessor Interface D Conversion and Access Time Over Temperature Range Read Mode... 2.5 µs Max D No External Clock or Oscillator Components Required D On-Chip Track and Hold D Single 5-V Supply D TLC0820A Is Direct Replacement for National Semiconductor ADC0820C/CC and Analog Devices AD7820K/B/T description The TLC0820AC and the TLC0820AI are Advanced LinCMOS ™ 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 µs 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/ µs 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.
