General Description
The MAX1076/MAX1078 are low-power, high-speed, seri-
al-output, 10-bit, analog-to-digital converters (ADCs) that
operate at up to 1.8Msps and have an internal reference.
These devices feature true-differential inputs, offering bet-
ter 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 MAX1076/MAX1078 operate from a single +4.75V to
+5.25V supply voltage. The MAX1076/MAX1078 include
a 4.096V internal reference. The MAX1076 has a unipolar
analog input, while the MAX1078 has a bipolar analog
input. These devices feature a partial power-down mode
and a full power-down mode for use between conver-
sions, which lower the supply current to 2mA (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 (±0.5 LSB INL) make the MAX1076/MAX1078
ideal for industrial process control, motor control, and
base-station applications.
The MAX1076/MAX1078 come in a 12-pin TQFN pack-
age, and are available in the extended (-40°C to +85°C)
temperature range.
