General Description
The MAX1302 multirange, low-power, 16-bit, succes-
sive-approximation, analog-to-digital converter (ADC)
operates from a single +5V supply and achieves
throughput rates up to 115ksps. A separate digital sup-
ply allows digital interfacing with a 2.7V to 5.25V system
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 1A (typ).
The MAX1302 provides eight (single-ended) or four
(true differential) analog input channels. Each analog
input channel is independently 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 MAX1302 also accepts an external
reference voltage between 3.800V and 4.136V.
The MAX1302 is available in a 24-pin TSSOP package
and is specified for operation from -40°C to +85°C.
