Data Sheet

FN4138.7

24-Bit, High Precis ion, Sigma Delta A/D

Converter

Features

• 20-Bit Resolution with No Missing Code

• 0.0015% Integral Non-Linearity (Typ)

• 20mV to ±2.5V Full Scale Input Ranges

• Internal PGIA with Gains of 1 to 128

• Serial Data I/O Interface, SPI Compatible

• Differential Analog and Reference Inputs

• Internal or System Calibration

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.

• 120dB Rejection of 60/50Hz Line Noise

• Settling Time of 4 Conversions (Max) for a Step Input

• Pb-Free Available (RoHS Compliant)

Applications

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 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.
