General Description
The MAX1274/MAX1275 low-power, high-speed, serial-
output, 12-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 MAX1274/MAX1275 operate from a single +4.75V to
+5.25V supply voltage and require an external reference.
The MAX1274 has a unipolar analog input, while the
MAX1275 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 1A (max), respectively. Also
featured is a separate power-supply input (VL), which
allows direct interfacing to +1.8V to VDD digital logic. The
fast conversion speed, low-power dissipation, excellent
AC performance, and DC accuracy (
±1 LSB INL) make
the MAX1274/MAX1275 ideal for industrial process con-
trol, motor control, and base-station applications.
The MAX1274/MAX1275 come in a 12-pin TQFN pack-
age, and are available in the extended (-40°C to +85°C)
temperature range.
