The AD4684/AD4685 are 16-bit, dual, simultaneous sampling, high speed, successive approximation register (SAR), analog-to-digital converters (ADCs) that operate from a 3.0 V to 3.6 V power supply and feature throughput rates of up to 1 MSPS for the AD4684 and 500 kSPS for the AD4685. The analog input types are single-ended and are sampled and converted on the falling edge of CS.The AD4684/AD4685 have an on-chip sequencer and integrated on-chip oversampling block to improve dynamic range and reduce noise at lower bandwidths. A buffered internal 2.5 V reference is included. Alternatively, an external reference up to 3.3 V can be used. The conversion process and data acquisition use standard control inputs, allowing interfacing to microprocessors or digital signal processors (DSPs). The AD4684/AD4685 is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces by using the separate logic supply. The AD4684/AD4685 are available in a 16-lead, 3 mm × 3 mm lead frame chip scale package (LFCSP) with operation specified from −40°C to +125°C.PRODUCT HIGHLIGHTS 4-channel, dual simultaneous sampling ADC.

The ADA4945-1 is a low noise, low distortion, fully differential amplifier with two selectable power modes. The device operates over a broad power supply range of 3 V to 10 V. The low dc offset, dc offset drift, and excellent dynamic performance of the ADA4945-1 makes it well suited for a variety of data acquisition and signal processing applications. The device is an ideal choice for driving high resolution, high performance successive approximation register (SAR) and Σ-Δ analog-to-digital converters (ADCs) on 4 mA of quiescent current (full power mode). The device can also be selected to operate on 1.4 mA of quiescent current (low power mode) to scale the power consumption to the desired performance necessary for an ADC drive application. The adjustable common-mode voltage allows the ADA4945-1 to match the input common-mode voltage of multiple ADCs. The internal common-mode feedback loop provides exceptional output balance, as well as suppression of even order harmonic distortion products.With the ADA4945-1, differential gain configurations are achieved with a simple external feedback network of four resistors determining the closed-loop gain of the amplifier. The ADA4945-1 is fabricated using Analog Devices, Inc., proprietary, silicon germanium (SiGe), complementary bipolar process, enabling the device to achieve low levels of distortion with an input voltage noise of only 1.8 nV/√Hz (full power mode).The ADA4945-1 is available in a RoHS-complaint, 3 mm × 3 mm, 16-lead LFCSP. The ADA4945-1 is specified to operate from −40°C to +125°C.Applications Low power Σ-Δ, PulSAR®, and SAR ADC drivers Single-ended to differential converters Differential buffers Medical imaging Process control Portable electronics

The ADL8105 is a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), pseudomorphic high electron mobility transistor (pHEMT), low noise wideband amplifier that operates from 5 GHz to 20 GHz.The ADL8105 provides a typical gain of 27 dB at 12 GHz to 17 GHz, a 1.8 dB typical noise figure from 12 GHz to 17 GHz, a typical output third-order intercept (OIP3) of 30.5 dBm at 12 GHz to 17 GHz, and a saturated output power (PSAT) of up to 20.5 dBm, requiring only 90 mA from a 5 V supply voltage. The power dissipation can be lowered at the expense of OIP3 and output power (POUT). The ADL8105 also features inputs and outputs that are internally matched to 50 Ω. The RFIN and RFOUT pins are internally ac-coupled, and the bias inductor is also integrated, making it ideal for surface-mounted technology (SMT)-based, high capacity microwave radio applications.The ADL8105 is housed in an RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP package.APPLICATIONSTelecommunicationsSatellite communicationsMilitary radarWeather radarElectronic warfareInstrumentation

The ADN4622/ADN4624 are quad-channel, signal isolated, low-voltage differential signaling (LVDS) buffers that operate at up to 2.5 Gbps with very low jitter. The devices integrate Analog Devices, Inc., iCoupler® technology, enhanced for high-speed operation to provide drop-in galvanic isolation of LVDS signal chains. AC coupling and/or level shifting to the LVDS receivers and from the LVDS drivers allows isolation of other high-speed signals such as current-mode logic (CML).The ADN4622/ADN4624 include a refresh mechanism to monitor the input and output states and ensure they remain the same in the absence of data transitions. For lower power consumption and high-speed operation with low jitter, the LVDS and isolator circuits rely on 1.8 V supplies. The ADN4622/ADN4624 are fully specified over a wide industrial temperature range and are available in a 28-lead, wide-body, finer pitch SOIC_W_FP package with 8.3 mm creepage and clearance (for 5.7 kV rms or 8 kVPEAK surge and impulse voltages and reinforced insulation at AC mains voltages) or 6 mm × 6 mm LFCSP package with 1.27 mm creepage and clearance (for basic/functional isolation).APPLICATIONS Isolated video and imaging data Analog front-end isolation Data plane isolation Isolated high speed clock and data links Multi-gigabit SERDES Board-to-board optical replacement (for example, short reach fiber)
