Description

The MAX1415/MAX1416 low-power, 2-channel, serial-output analog-to-digital converters (ADCs) use a sigma-delta modulator with a digital filter to achieve 16-bit resolution with no missing codes. These ADCs are pin-compatible upgrades to the MX7705/AD7705. The MAX1415/MAX1416 feature an internal oscillator (1MHz or 2.4576MHz), an on-chip input buffer, and a programmable gain amplifier (PGA). The devices offer an SPI™-/QSPI™-/MICROWIRE™-compatible serial interface.

The MAX1415 requires a single 2.7V to 3.6V supply, and the MAX1416 requires a single 4.75V to 5.25V supply. The operating supply current is 400µA (max) with a 3V supply. Power-down mode reduces the supply current to 2µA (typ). When operating with a supply of 3V, the power dissipation is less than 1.44mW, making the MAX1415 ideal for battery-powered applications.

Self-calibration and system calibration allow the MAX1415/MAX1416 to correct for gain and offset errors. Excellent DC performance (±0.0015% FSR INL) and low noise (700nV in unbuffered mode) make the MAX1415/MAX1416 ideal for measuring low-frequency signals with a wide dynamic range. These devices accept fully differential bipolar/unipolar inputs. An internal input buffer allows for input signals with high source impedances. An on-chip digital filter, with a programmable cutoff and output data rate, processes the output of the sigma-delta modulator. The first notch frequency of the digital filter is chosen to provide 150dB rejection of common-mode 50Hz or 60Hz noise and 98dB rejection of normal-mode 50Hz or 60Hz noise. A PGA and digital filtering allow signals to be directly acquired with little or no signal-conditioning requirements.

The MAX1415/MAX1416 are available in 16-pin PDIP, wide SO, and TSSOP packages.
