Analog-to-Digital Converters Provide Low-Power Operation

Wed, 01/14/2009 - 9:43am


Microchip Technology, Inc. announces its series of low-power, high-resolution Delta-Sigma analog-to-digital converters (ADCs). The MCP3422, MCP3423 and MCP3424 (MCP3422/3/4) ADCs provide 18-bits of resolution, and they consume only 135 mA at 3 V continuous conversion. The multi-channel devices have integrated voltage references, programmable gain amplifiers (PGA) and oscillators onboard, and they are available in small packages of 2 × 3 mm DFN. They are suitable for portable measurement applications in the industrial, medical, consumer and automotive markets. The ADCs' low current consumption enables the end application to use less power, resulting in longer battery life. With their integrated PGAs, voltage references and oscillators, they eliminate the need for numerous external components, providing a smaller overall design footprint.
