Low-power high-SMR 24-bit delta-sigma analog-to-digital converter

Achieving a high signal-to-noise ratio, the low-power 24-bit Maxim MAX11216 64ksps delta-sigma analog-to-digital converter (ADC) is now available from Mouser. The device targets applications such as ATE, high-precision portable sensors, medical equipment, scientific instrumentation and seismic data acquisition. The device feature sample rates up to 64ksps allowing both precision DC and AC measurements. Integral nonlinearity is 'guaranteed' to 4ppm maximum. The MAX11216 communicates via an SPI-compatible serial interface and is available in a small 24-pin TSSOP package. The MAX11216 offers a programmable gain amplifier with gain settings between 1x to 128x. Optional buffers are also included to provide isolation of the signal inputs from the switched capacitor sampling network. This allows the MAX11216 to be used with high-impedance sources without compromising available dynamic range. The MAX11216 operates from a single 2.7V to 3.6V analog supply, or split ±1.8V analog supplies, allowing the analog input to be sampled below ground. The digital supply range is 2V to 3.6V, allowing communication with 2.5V, 3V, or 3.3V logic.
