General Description
The MAX1300/MAX1301 multirange, low-power, 16-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 MAX1300 provides eight (single-ended) or four (true
differential) analog input channels. The MAX1301 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 [0 to (3 x V
REF
)/2, (-3 x V
REF
)/2 to 0, 0 to 3

] and three differential input ranges [(±3 x V
REF
)/2,
±3 x V
REF
, ±6 x V
REF
].
An on-chip +4.096V reference offers a small convenient
ADC solution. The MAX1300/MAX1301 also accept an
external reference voltage between 3.800V and 4.136V.
The MAX1300 is available in a 24-pin TSSOP package
and the MAX1301 is available in a 20-pin TSSOP pack-
age. Each device is specified for operation from -40°C to
+85°C.
