AD13280AF

Dual-Channel, 12-Bit, 80 MSPS ADC with Analog Input Signal Conditioning

Analog Devices 

GENERAL DESCRIPTION

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 fil-

tering. The AD13280 also offers users a choice of analog input

AD13280

signal ranges to further minimize additional external signal

conditioning, while remaining general purpose.

The AD13280 operates with ±5.0 V for the analog signal condi-

tioning 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).
