AD13280: Dual-Channel, 12-Bit, 80MSPS A/D Converter with Analog Input Signal Conditioning
The AD13280 is a complete, dual-channel, signal processing solution that includes on-board amplifiers, references, ADCs, and output termination components to provide optimized system performance. The AD13280 has on-chip track-and-hold circuitry and uses an innovative multipass architecture to achieve 12-bit, 80 MSPS performance. The AD13280 uses innovative high density circuit design and laser-trimmed thin-film resistor networks to achieve exceptional channel matching, impedance control, and performance while maintaining excellent isolation and providing for significant board area savings.
Multiple options are provided for driving the analog input, including single-ended, differential, and optional series filtering. The AD13280 also offers users a choice of analog input signal ranges to further minimize additional external signal conditioning, while remaining general purpose.
TheAD13280 operates with ±5.0 V for the analog signal conditioning with a separate 5.0 V supply for the analog-to-digital conversion and 3.3 V digital supply for the output stage. Each channel is completely independent, allowing operation with independent encode and analog inputs and maintaining minimal crosstalk and interference.The AD13280 is available in a 68-lead, ceramic gull wing package. The components are manufactured using the Analog Devices, Inc., high speed complementary bipolar process (XFCB).
