The AD7616 is a 16-bit, DAS that supports dual simultaneous sampling of 16 channels. The AD7616 operates from a single 5 V supply and can accommodate ?10 V, ?5 V, and ?2.5 V true bipolar input signals while sampling at throughput rates up to 1 MSPS per channel pair with 90.5 dB SNR. Higher SNR performance can be achieved with the on-chip oversampling mode (92 dB for an oversampling ratio (OSR) of 2).The input clamp protection circuitry can tolerate voltages up to ?21 V. The AD7616 has 1 M? analog input impedance, regardless of sampling frequency. The single-supply operation, on-chip filtering, and high input impedance eliminate the need for driver op amps and external bipolar supplies.The device contains analog input clamp protection, a dual, 16-bit charge redistribution SAR analog-to-digital converter (ADC), a flexible digital filter, a 2.5 V reference and reference buffer, and high speed serial and parallel interfaces.The AD7616 is serial peripheral interface (SPI)/QSPI?/DSP/ MICROWIRE compatibleApplications Power line monitoring Protective relays Multiphase motor control Instrumentation and control systems Data acquisition systems (DASs)

The LTC3603 is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a constant-frequency, current mode architecture. It operates from an input voltage range of 4.5V to 15V and provides an adjustable regulated output voltage from 0.6V to 14.5V while delivering up to 2.5A of output current. The internal synchronous power switch with 45m? on-resistance increases efficiency and eliminates the need for an external Schottky diode. The switching frequency can either be set by an external resistor or synchronized to an external clock. OPTI-LOOP? compensation allows the transient response to be optimized over a wide range of loads and output capacitors.The LTC3603 can be configured for either Burst Mode operation or forced continuous operation. Forced continuous operation reduces noise and RF interference, while Burst Mode operation provides the highest efficiency at light loads. In Burst Mode operation, external control of the burst clamp level allows the output voltage ripple to be adjusted according to the requirements of the application.Applications Point-of-Load Supplies Portable Instruments Communications Infrastructure

Fixed LC networks on the LO and RF ports cover a continuous 90MHz to 1300MHz range. The SPI interface controls the supply current, modulator gain, and allows optimization of the LO carrier feedthrough and side-band suppression.
