HI7191
24-Bit, High Precision, Sigma Delta A/D
Converter
The Intersil HI7191 is a monolithic instrumentation, sigma
delta A/D converter which operates from
±5V supplies. Both
the signal and reference inputs are fully differential for
maximum flexibility and performance. An internal
Programmable Gain Instrumentation Amplifier (PGIA)
provides input gains from 1 to 128 eliminating the need for
external pre-amplifiers. The on-demand converter
auto-calibrate function is capable of removing offset and gain
errors existing in external and internal circuitry. The on-board
user programmable digital filter provides over 120dB of
60/50Hz noise rejection and allows fine tuning of resolution
and conversion speed over a wide dynamic range. The
HI7190 and HI7191 are functionally the same device, but the
HI7190 has tighter linearity specs.
The HI7191 contains a serial I/O port and is compatible with
most synchronous transfer formats including both the
Motorola 6805/11 series SPI and Intel 8051 series SSR
protocols. A sophisticated set of commands gives the user
control over calibration, PGIA gain, device selection, standby
mode, and several other features. The On-chip Calibration
Registers allow the user to read and write calibration data.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
*Pb-free PDIPs can be used for through hole wave solder processing
only. They are not intended for use in Reflow solder processing
applications.
