I am a software engineer and have limited knowledge of electronics. I am using a Raspberry PI to control a AD5360 ADC eval board (http://www.analog.com/en/products/digital-to-analog-converters/da-converters/ad5360.html#product-overview).
I need to attenuate +-5 volt output form the DAC to +-50 Microvolts on 16 independent channels.
I am thinking that I need an on chip attenuator. I am still prototyping so and part needs to be used on a bread board or with pins that can be soldered to a solder board. I need a fast response time because I change voltage on each of the 16 channels between 256 to 2048 time each second, and a high level of precision. If required I could build them, however because I need 16 I would prefer to buy them. I have tried to use a simple voltage divider however, this introduces too much variance at the microvolt range.
I am open to other ideas if they can solve the problem more efficiently or are more cost effective.
