PSoC precision analog development kit highlights 20-bit ADC with micro-volt measurements and differential inputs

December 06, 2011 // By Paul Buckley
Cypress Semiconductor Corp. has released the company's new CY8CKIT-025 Development Kit for its PSoC 3 and PSoC 5 programmable system-on-chip architectures. The new kit highlights PSoC's 8- to 20-Bit Delta-Sigma ADC with an internal voltage reference of +- 0.1%, a sampling rate of up to 384 ksps, and up to 18-bit effective number of bits (ENOB) performance.

The kit showcases the capability for measurements in microvolts enabled by a precision of 0.003 percent. In addition, the ADC enables designers to implement both differential and single-ended inputs for the Delta Sigma ADC and claims to provide unmatched flexibility in interfacing with sensors of varying output types.     

Another differentiating feature of PSoC 3 and PSoC 5's Delta Sigma ADC is that designers can easily configure it with a wide range of resolutions, sample rates, and input buffer and gain modes. This is easily accomplished using the Graphical User Interface inside Cypress's PSoC Creator IDE. The pre-written software “components” in PSoC Creator allow a user to graphically select the desired values, greatly simplifying device configuration.     

The new kit includes each of four different types of analog temperature sensors, including a thermocouple, a diode, a thermistor and a resistance temperature detector (RTD). The kit also includes a bonus CY8CKIT-012 PSoC Prototyping and Development Expansion Board.        


The new CY8CKIT-025 is available today.   

Designers can buy the new development kit for $115 at
