Technical Support www.analog.com FEATURES Dual, 65 MSPS minimum sample rate Channel-to-channel matching, ±0.5% gain error Channel-to-channel isolation, >90 dB DC-coupled signal conditioning included Selectable bipolar input voltage range (±0.5 V, ±1.0 V, ±2.0 V) Gain flatness up to 25 MHz: <0.2 dB 80 dB spurious-free dynamic range Twos complement output format 3.3 V or 5 V CMOS-compatible output levels 1.75 W per channel Industrial and military grade APPLICATIONS Phased array receivers Communications receivers FLIR processing Secure communications GPS antijamming receivers Multichannel, multimode receivers GENERAL DESCRIPTION The AD10465 is a full channel ADC solution with on-module signal conditioning for improved dynamic performance and fully matched channel-to-channel performance. The module includes two wide dynamic range AD6644 ADCs. Each AD6644 has a dc-coupled amplifier front end including an AD8037 low distortion, high bandwidth amplifier that provides high input impedance and gain and drives the AD8138 single- to-differential amplifier. The AD6644s have on-chip track-and- hold circuitry and utilize an innovative multipass architecture to achieve 14-bit, 65 MSPS performance. The AD10465 uses innovative high density circuit design and laser trimmed, thin film resistor networks to achieve exceptional matching and performance, while still maintaining excellent isolation and providing for significant board area savings. The AD10465 operates with ±5.0 V supplies 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. The AD10465 also offers the user a choice of analog input signal ranges to further minimize additional external signal conditioning, while remaining general-purpose. The AD10465 is packaged in a 68-lead ceramic leaded chip carrier package, footprint-compatible with the earlier generation AD10242 (12-bit, 40 MSPS) and AD10265 (12-bit, 65 MSPS). Manufacturing is done on the Analog Devices Mil- 38534 Qualified Manufacturers Line (QML) and components are available up to Class-H (−40°C to +85°C). The AD6644 internal components are manufactured on Analog Devices’ high speed complementary bipolar process (XFCB). PRODUCT HIGHLIGHTS 1. Guaranteed sample rate of 65 MSPS. 2. Input amplitude options, user configurable. 3. Input signal conditioning included; both channels matched for gain. 4. Fully tested/characterized performance. 5. Footprint-compatible family; 68-lead CLCC package.
