ADC-321 General Description
The ADC-321 is an 8-bit, high speed, monolithic CMOS, sub-ranging A/D converter. The ADC-321 achieves a sampling rate comparable to flash converters by employing a sub-ranging technique which uses multiple comparator blocks each containing a sample-and-hold amplifier. The ADC-321 can operate with either a single +5V or dual +5V and +3.3V power source to allow easy interfacing with 3.3V logic.
An optional synchronous clamp function useful for video signal processing is provided. The ADC-321 is well suited for the portable video signal processors due to its low 125mW typical power dissipation. The ADC-321 also features ±0.5 LSB max. differential non-linearity, a self bias function that can eliminate the need for external references, SNR with THD of 45dB, a small 32-pin QFP package and an operating temperature range of 40 to +85°C
