1.8Msps, Single-Supply, Low-Power,  
True-Differential, 10-Bit ADCs  
General Description  
Features  
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.  
ꢀ 1.8Msps Sampling Rate  
ꢀ Only 45mW (typ) Power Dissipation  
ꢀ Only 1µA (max) Shutdown Current  
ꢀ High-Speed, SPI-Compatible, 3-Wire Serial Interface  
ꢀ 61dB S/(N + D) at 525kHz Input Frequency  
ꢀ Internal True-Differential Track/Hold (T/H)  
ꢀ External Reference  
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  
ꢀ No Pipeline Delays  
ꢀ Small 12-Pin TQFN Package  
featured is a separate power-supply input (V ), which  
L
allows direct interfacing to +1.8V to V  
digital logic. The  
DD  
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.
