EVALUATION KIT AVAILABLE MAX11200/MAX11210 24-Bit, Single-Channel, Ultra-Low-Power, Delta-Sigma ADCs with GPIO General Description Benefits and Features The MAX11200/MAX11210 are ultra-low-power (< 300FA Minimize Power Consumption with Ultra-Low Power active current), high-resolution, serial output ADCs. These Dissipation devices provide the highest resolution per unit power in Operating-Mode Current Drain < 300A (max) the industry, and are optimized for applications that Sleep-Mode Current Drain < 0.4A require very high dynamic range with low power, such as Improve Measurement Quality with Excellent DC/AC sensors on a 4mA to 20mA industrial control loop. Optional Accuracy input buffers provide isolation of the signal inputs from the 24.0-Bit ENOB at 5sps switched capacitor sampling network allowing these con- 20.9-Bit Noise-Free Resolution at 10sps verters to be used with high-impedance sources without 19-Bit Noise-Free Resolution at 120sps compromising available dynamic range or linearity. The 570nV Noise at 10sps, 3.6VFS Input RMS devices provide a high-accuracy internal oscillator that 1ppm INL (typ), 10ppm (max) and No Missing Codes requires no external components. When used with the Lower System Cost with Integrated Functionality specified data rates, the internal digital filter provides Programmable Gain (1 to 16) (MAX11210) more than 100dB rejection of 50Hz or 60Hz line noise. Four SPI-Controlled GPIOs for External Mux Control The devices are configurable using the SPI interface and Optional Input Buffers on Both Signal and are available in a 16-pin QSOP package.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
