8-/4-Channel, ±VREF Multirange Inputs,
Serial 14-Bit ADCs
General Description
The MAX1034/MAX1035 multirange, low-power, 14-bit,
successive-approximation, analog-to-digital converters
(ADCs) operate from a single +5V supply and achieve
throughput rates up to 115ksps. A separate digital sup-
ply allows digital interfacing with 2.7V to 5.25V systems
using the SPI-/QSPI™-/MICROWIRE®-compatible serial
interface. Partial power-down mode reduces the supply
current to 1.3mA (typ). Full power-down mode reduces
the power-supply current to 1µA (typ).
The MAX1034 provides eight (single-ended) or four (true
differential) analog input channels. The MAX1035 pro-
vides four (single-ended) or two (true differential) analog
input channels. Each analog input channel is indepen-
dently software programmable for seven single-ended
input ranges (0V to +VREF/2, -VREF/2 to 0V, 0V to +VREF,
-VREF to 0V, ±VREF/4, ±VREF/2, and ±VREF), and three
differential input ranges (±VREF/2, ±VREF, ±2 x VREF).
An on-chip +4.096V reference offers a small convenient
ADC solution. The MAX1034/MAX1035 also accept an
external reference voltage between 3.800V and 4.136V.
The MAX1034 is available in a 24-pin TSSOP package
and the MAX1035 is available in a 20-pin TSSOP pack-
age. Each device is specified for operation from -40°C
to +85°C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
