8-Bit, 392 kSPS ADC Parallel Out, Microprocessor Peripheral, On-Chip Track-and-Hold, Single Channels

TLC0820ACN General Description

The TLC0820ACN is an Advanced LinCMOS 8-bit analog-to-digital converter that offers high-speed performance and low power consumption. With two 4-bit flash converters, a 4-bit digital-to-analog converter, a summing (error) amplifier, control logic, and a result latch circuit, this device is designed to deliver precise and efficient conversion of analog signals into digital data. The modified flash technique enables the TLC0820ACN to complete an 8-bit conversion in just 1.18 microseconds across a wide temperature range, making it suitable for applications requiring fast response times
