Analog Devices Inc. AD9094 Quad Analog-to-Digital Converters

Analog Devices Inc. AD9094 Quad Analog-to-Digital Converters is a quad, 8-bit, 1 GSPS analog-to-digital converter (ADC). The AD9094 devices have an on-chip buffer and a sample-and-hold circuit. The circuit is designed for low power, small size, and ease of use. This device is designed for sampling wide bandwidth analog signals of up to 1.4GHz. The AD9094 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.
