4-/6-/8-Channel, 16-Bit, Simultaneous-Sampling
Bipolar ADCs

Industry's first single-supply bipolar ADCs with high-impedance input!


Maxim Integrated's IC MAX11044, MAX11045, and MAX11046 are the industry's first single-supply bipolar ADCs with high-impedance input. These Maxim Integrated IC 16-bit bipolar ADCs offer 4, 6, or 8 independent input channels, feature independent track and hold and SAR circuitry, and provide simultaneous sampling at 250ksps for each channel. The MAX11044, MAX11045, and MAX11046 accept a ±5V input with all inputs overrange protected with internal ±20mA input clamps providing overrange protection with a simple external resistor. The Maxim Integrated IC 1104x ADC series operates with a 4.75V to 5.25V analog supply and a separate flexible 2.7V to 5.25V digital supply for interfacing with the host without a level shifter.
