+2.7V, Low-Power, 8-Channel,

Serial 12-Bit ADCs

General Description

____________________________Features

The MAX146/MAX147 12-bit data-acquisition systems

combine an 8-channel multiplexer, high-bandwidth

track/hold, and serial interface with high conversion

speed and low power consumption. The MAX146 oper-

ates from a single +2.7V to +3.6V supply; the MAX147

operates from a single +2.7V to +5.25V supply. Both

devices’ analog inputs are software configurable for

unipolar/bipolar and single-ended/differential operation.

ꢀ 8-Channel Single-Ended or 4-Channel

Differential Inputs

ꢀ Single-Supply Operation

+2.7V to +3.6V (MAX146)

+2.7V to +5.25V (MAX147)

ꢀ Internal 2.5V Reference (MAX146)

ꢀ Low Power

The 4-wire serial interface connects directly to SPI™/

QSPI™ and MICROWIRE™ devices without external

logic. A serial strobe output allows direct connection to

TMS320-family digital signal processors. The

MAX146/MAX147 use either the internal clock or an exter-

nal serial-interface clock to perform successive-approxi-

mation analog-to-digital conversions.

1.2mA (133ksps, 3V supply)

54µA (1ksps, 3V supply)

1µA (power-down mode)

ꢀ SPI/QSPI/MICROWIRE/TMS320-Compatible

4-Wire Serial Interface

ꢀ Software-Configurable Unipolar or Bipolar Inputs

The MAX146 has an internal 2.5V reference, while the

MAX147 requires an external reference. Both parts have

a reference-buffer amplifier with a 1.5ꢀ voltage-

adjustment range.

ꢀ 20-Pin DIP/SSOP Packages

Ordering Information

INL

These devices provide a hard-wired SHDN pin and a

software-selectable power-down, and can be pro-

grammed to automatically shut down at the end of a con-

version. Accessing the serial interface automatically

powers up the MAX146/MAX147, and the quick turn-on

time allows them to be shut down between all conver-

sions. This technique can cut supply current to under

60µA at reduced sampling rates.
