4-/6-/8-Channel, 16-/14-Bit, Simultaneous-Sampling ADCs

Industry's First Single-Supply Bipolar ADCs with High-Impedance Input

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.

Description

The MAX11046 evaluation kit (EV kit) provides a proven design to evaluate the MAX11046 8-channel, 16-bit, simultaneous-sampling ADC. The EV kit also includes Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX11046.

The MAX11046 EV kit PCB comes with a MAX11046ETN+ installed. The MAX11046 EV kit can also be used to evaluate the MAX11044, MAX11045, MAX11047, MAX11048, and MAX11049. Contact the factory for free samples of the pin-compatible MAX11044ETN+, MAX11045ETN+, MAX11047ETN+, MAX11048ETN+, and MAX11049ETN+ to evaluate these parts.
