General Description
The MAX1072/MAX1075 low-power, high-speed, serial-
output, 10-bit, analog-to-digital converters (ADCs) oper-
ate at up to 1.8Msps. These devices feature true-differen-
tial inputs, offering better noise immunity, distortion
improvements, and a wider dynamic range over single-
ended inputs. A standard SPI/QSPI/MICROWIRE
interface provides the clock necessary for conversion.
These devices easily interface with standard digital signal
processor (DSP) synchronous serial interfaces.
The MAX1072/MAX1075 operate from a single +4.75V to
+5.25V supply voltage and require an external reference.
The MAX1072 has a unipolar analog input, while the
MAX1075 has a bipolar analog input. These devices fea-
ture a partial power-down mode and a full power-down
mode for use between conversions, which lower the sup-
ply current to 1mA (typ) and 1μA (max), respectively. Also
featured is a separate power-supply input (V
L
), which
allows direct interfacing to +1.8V to V
DD
digital logic. The
fast conversion speed, low-power dissipation, excellent
AC performance, and DC accuracy (
±
0.5 LSB INL) make
the MAX1072/MAX1075 ideal for industrial process con-
trol, motor control, and base-station applications.
The MAX1072/MAX1075 come in a 12-pin TQFN pack-
age, and are available in the commercial (0°C to +70°C)
and extended (-40°C to +85°C) temperature ranges.
