The CS5530 offers users of the popular CS5531/32/33/34 family of integrated Delta-Sigma A/D Converters a lower-cost option – while offering the same low-noise performance and output word-rate flexibility – but with a reduced feature set.
With a single differential input channel and a fixed gain of 64x in the high-performance chopper-stabilized instrumentation amplifier, noise performance is a very low 12 nV/√Hz at 0.01 Hz. Digital scaling is also available, which can provide additional effective gain of up to 40. The Delta-Sigma modulator is identical to that used throughout the product family and features the same excellent 50/60 Hz rejection. The range of user-selectable output word rates is also unchanged, with 20 rates between 6.25 and 3,840 samples per second (SPS) when operating from a 4.9152 MHz Master Clock.
With a simple 3-wire SPI and microwire-compatible serial interface, the CS5530 is easily connected to most popular microcontrollers. The combination of industry-leading performance and reduced feature set provides a low-cost alternative to this popular family of products, making the CS5530 an excellent solution in cost-sensitive weigh scale, temperature controller, digital panel meter, and similar industrial monitoring and control applications.
