Microchip Technology Inc announces a resolution analog-to-digital converter (ADC) available in a SOT-23 package. The low-power, 18-bit, Delta-Sigma MCP3421 ADC features an integrated voltage reference and Programmable Gain Amplifier (PGA) on-chip, which reduces the need for external components and enables a smaller overall design footprint. With its 6-pin package, low power consumption and high resolution, the new ADC is ideal for portable measurement applications in the industrial, medical, consumer and automotive markets. The MCP3421 ADC uses an I2C™ compatible serial interface and operates from a single power supply (2.7 to 5.5 V). Microchip's low-power technology enables the device's extremely low power consumption of just 155 microAmperes at 5 V continuous conversion, which helps to extend battery life in portable measurement devices. Additionally, with the device's onboard PGA, users can select the gains of x1, x2, x4 or x8 before the analog-to-digital conversion takes place, enabling very high-resolution conversion of even small input signals. The integrated voltage reference and oscillator lessen the need for external components, resulting in simpler designs and a smaller overall design footprint.
