CS5530

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 main 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.
