♦ 12-Bit Resolution, 1/2LSB Linearity

♦ Single +5V Operation

♦ Software-Selectable Input Ranges:

±10V, ±5V, 0V to 10V, 0V to 5V

The MAX197 multi-range, 12-bit data-acquisition sys-

tem (DAS) requires only a single +5V supply for opera-

tion, yet accepts signals at its analog inputs that may

s p a n b oth a b ove the p owe r-s up p ly ra il a nd b e low

ground. This system provides 8 analog input channels

that are independently software programmable for a

variety of ranges: ±10V, ±5V, 0V to +10V, or 0V to +5V.

This increases effective dynamic range to 14 bits, and

provides the user flexibility to interface 4mA-to-20mA,

±12V, and ±15V powered sensors to a single +5V sys-

tem. In addition, the converter is overvoltage tolerant to

±16.5V; a fault condition on any channel will not affect

the conversion result of the selected channel. Other

fe a ture s inc lud e a 5MHz b a nd wid th tra c k/hold , a

100ksps throughput rate, software-selectable internal or

external clock and acquisition, 8+4 parallel interface,

and an internal 4.096V or an external reference.

♦ Fault-Protected Input Multiplexer (±16.5V)

♦ 8 Analog Input Channels

♦ 6µs Conversion Time, 100ksps Sampling Rate

♦ Internal or External Acquisition Control

♦ Internal 4.096V or External Reference

♦ Two Power-Down Modes

♦ Internal or External Clock

A hardware SHDN pin and two programmable power-

down modes (STBYPD, FULLPD) are provided for low-

current shutdown between conversions. In STBYPD

mode, the reference buffer remains active, eliminating

start-up delays.

28 Wide SO

28 SSOP

The MAX197 employs a standard microprocessor (µP)

interface. A three-state data I/O port is configured to

operate with 8-bit data buses, and data-access and

bus-release timing specifications are compatible with

most popula r µPs. All logic inputs a nd outp uts a re

TTL/CMOS compatible.
