General Description
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 con-
struction 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-selec-
table 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.
