MAX11043ATL+ by Analog Devices

4-Channel, 16-Bit, Simultaneous Sampling ADCs with PGA, Filter, and 8-/12-Bit Dual-Stage DAC


The MAX11043 features 4 single-ended or differential channels of simultaneous-sampling ADCs with 16-bit resolution. The MAX11043 contains a versatile filter block and programmable-gain amplifier (PGA) per channel. The filter consists of seven cascaded 2nd-order filter sections for each channel, allowing the construction of a 14th-order filter. The filter coefficients are user-programmable. Configure each 2nd-order filter as lowpass (LP), highpass (HP), or bandpass (BP) with optional rectification. Gain and phase mismatch of the analog signal path is better than -50dB. The ADC can digitize signals up to 200kHz. A 40MHz serial interface provides communication to and from the device. The SPI interface provides throughput of 1600ksps; 4 channels at 400ksps per channel or 2 channels at 800ksps per channel. A software-selectable scan mode allows reading the ADC results while simultaneously updating the DAC. Other features of the MAX11043 include an internal (+2.5V) or external (+2.0V to +2.8V) reference, power-saving modes, and a PGA with gains of 1 to 64. The PGA includes an equalizer (EQ) function that automatically boosts low-amplitude, high-frequency signals for applications such as CW-chirp radar. The MAX11043 includes two 8-bit coarse DACs that set the high and low references for a second-stage 12-bit fine DAC, typically used for VCO control. Use software controls to write to the DAC or step the DAC up and down under hardware control in programmable steps. The device operates from a +3.0V to +3.6V supply. The MAX11043 is available in a 40-pin, 6mm x 6mm TQFN package and operates over the extended -40°C to +125°C temperature range.
