描述 The TLC0820AC and the TLC0820AI are Advanced LinCMOSTM 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.特性 Advanced LinCMOSTM Silicon-Gate Technology 8-Bit Resolution Differential Reference Inputs Parallel Microprocessor Interface Conversion and Access Time Over Temperature Range Read Mode . . . 2.5 us Max No External Clock or Oscillator Components Required On-Chip Track and Hold Single 5-V Supply TLC0820A Is Direct Replacement for National Semiconductor ADC0820C/CC and Analog Devices AD7820K/B/TAdvanced LinCMOS is a trademark of Texas Instruments Incorporated.
