8-channel, 16-bit simultaneous-sampling ADCs from Maxim

Maxim has introduced the MAX11046, a new 8-channel, 16-bit simultaneous-sampling ADC that provides a low-noise, on-chip, and negative supply voltage. The MAX11046 device 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, and suitable for automatic test equipment, multiphase motor control, power-factor monitoring and correction, power-grid protection, vibration and waveform analysis.

The MAX11046 provides a high-impedance bipolar input and only requires a single positive voltage to operate. The high-impedance input also avoids the cost precision operational amplifier found in traditional designs.

The key features of the MAX11046 ADCs are,

Up to 1Gohm high-impedance inputs
On-chip T/H circuit for each channel
Fast 3µs conversion time
High throughput of 250ksps for All 8 Channels
16-Bit, high-speed, parallel interface
Internal clocked conversions
10ns of aperture delay
100ps of channel-to-channel T/H matching
Low drift, accurate 4.096V internal reference providing an input range of ±5V
External reference range of 3.0V to 4.25V

All inputs are overrange protected with internal ±20mA input clamps providing overrange protection with a simple external resistor. The other features include a 4MHz T/H input bandwidth, internal clock, and internal or external reference.

Maxim says, the MAX11046 ADC exceeds the combined IEC 62053 Class 0.2 and meets the 6kV transient voltage specification of EN 50160.

Package: Lead-free, 56-pin TQFN package
Price: Starts at $15.90 for 1k pieces
Availability: Evaluation kit is available now
