Product Details

The MAX11044/MAX11044B/MAX11045/MAX11045B/MAX11046/MAX11046B 16-bit and MAX11054/MAX11055/MAX11056 14-bit ADCs offer 4, 6, or 8 independent input channels. Featuring independent track and hold (T/H) and SAR circuitry, these parts provide simultaneous sampling at 250ksps for each channel.
The MAX11044/MAX11044B/MAX11045/MAX11045B/MAX11046/MAX11046B and MAX11054/MAX11055/MAX11056 accept a ±5V input. All inputs are overrange protected with internal ±20mA input clamps providing overrange protection with a simple external resistor. Other features include a 4MHz T/H input bandwidth, internal clock, and internal or external reference. A 20MHz, bidirectional, parallel interface provides the conversion results and accepts digital configuration inputs.
The MAX11044/MAX11044B/MAX11045/MAX11045B/MAX11046/MAX11046B and MAX11054/MAX11055/MAX11056 operate 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. The MAX11044/MAX11044B/MAX11045/MAX11045B/MAX11046/MAX11046B are available in a 56-pin TQFN and 64-pin TQFP packages while the MAX11054/MAX11055/MAX11056 are available in TQFP only and operate over the extended -40°C to +85°C temperature range.
