19-3051; Rev 0; 10/03 16-Bit, Low-Power, 2-Channel, Sigma-Delta ADC General Description The MX7705 low-power, 2-channel, serial-output analog-to-digital converter (ADC) includes a sigma-delta modulator with a digital filter to achieve 16-bit resolution with no missing codes. This ADC is pin compatible and software compatible with the AD7705. The MX7705 features an on-chip input buffer and programmable-gain amplifier (PGA). The device offers an SPI-/QSPI-/ MICROWIRE-compatible serial interface. The MX7705 operates from a single 2.7V to 5.25V supply. The operating supply current is 320µA (typ) with a 3V supply. Power-down mode reduces the supply current to 2µA (typ). Self-calibration and system calibration allow the MX7705 to correct for gain and offset errors.
