MAX1415/MAX1416
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 program-
mable 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 differ-
ential 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 out-
put 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 sig-
nals to be directly acquired with little or no signal-condi-
tioning requirements.
The MAX1415/MAX1416 are available in 16-pin PDIP,
SO, and TSSOP packages.
