Part Number: AD5370

Function: 40-Channel, 16-Bit, Serial Input, Voltage Output DAC

Package: 64-lead LFCSP and a 64-lead LQFP Type

Manufacturer: Analog Devices

Description:

The AD5370 contains forty 16-bit DACs in a single 64-lead LFCSP and a 64-lead LQFP. The device provides buffered voltage outputs with a span that is 4× the reference voltage. The gain and offset of each DAC channel can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs.

Three offset DAC channels allow the output range of blocks to be adjusted. Group 0 can be adjusted by Offset DAC 0, Group 1 can be adjusted by Offset DAC 1, and Group 2 to Group 4 can be adjusted by Offset DAC 2. The AD5370 offers guaranteed operation over a wide supply range, with VSSfrom −16.5 V to −4.5 V and VDDfrom +9 V to +16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.

Description:

The AD7714, AD7714YRUZ is a complete analog front end for low-frequency measurement applications. The device accepts low level signals directly from a transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 24 bits of no missing codes performance. The input signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by an onchip digital filter. The first notch of this digital filter can be programmed via the on-chip control regist
