Dialog Semiconductor unveils SLG47004 GreenPAK first fully programmable advanced analog system IC

17 November 2020

Dialog Semiconductor has launched the SLG47004 as its first Advanced Analog GreenPAK integrated circuit (IC). The SLG47004 integrates an instrumentation amplifier with auto-trimming, digital pots, analog switches and myriad digital functions with in-system programmability in a small 3 mm x 3 mm solution size allowing designers to create, simulate and prototype their own unique sophisticated analog ICs in minutes at a lower cost than a discrete component implementation.

Similar to the other members of the GreenPAK family, the SLG47004 is highly customizable where a vast array of new functions can be simply created by the designer. For example, the SLG47004 includes low offset complementary metal–oxide semiconductor operational amplifiers (op amps) with an 8 MHz bandwidth that can be configured into an instrumentation amplifier. The digital potentiometers can be used for auto-trimming the Source: Dialog SemiconductorSource: Dialog Semiconductoranalog system offset or used independently as 10 bit 100 kOhm digital rheostats. All this flexible programmability is combined to form a single IC system solution for implementing cost-effective and energy-efficient complete analog system solutions or an advanced analog front end (AFE).

The SLG47004 is an ideal replacement for designs that include programmable gain amplifiers, instrumentation amplifiers, digital potentiometers and analog switches. The common applications for the SLG47004 include analog interfaces for sensors, AFEs for analog-to-digital converters and tunable analog filters. Other potential sensor interface applications include pressure sensors, photo detectors and force-sensitive button interfaces.

The GreenPAK Designer software package for the SLG47004 allows for fast, accurate and complete analog simulation of the op amps, digital pots, analog switches, comparators and all digital blocks including some external system components. This allows the designer to simulate circuit nodes both inside and outside the IC. Upon completion of a design, a sample can be easily generated in minutes via the GreenPAK Designer hardware programmer.

The SLG47004 is sampling now and will be in production in the first quarter of 2021.
