General Description
The 16-bit CS5525 and the 20-bit CS5526 are highly in-
tegrated
Σ A/D converters which include an
instrumentation amplifier, a PGA (programmable gain
amplifier), eight digital filters, and self and system cali-
bration circuitry.
The converters are designed to provide their own nega-
tive supply which enables their on-chip instrumentation
amplifiers to measure bipolar ground-referenced signals
≤±100 mV. By directly supplying NBV with -2.5 V and
with VA+ at 5 V, ±2.5 V signals (with respect to ground)
can be measured.
The digital filters provide programmable output update
rates between 3.76 Sps to 202 Sps (XIN = 32.768 kHz).
Output word rates can be increased by approximately 3X
by using XIN = 100 kHz. Each filter is designed to settle
to full accuracy for its output update rate in one conver-
sion cycle. The filters with word rates of 15 Sps or less
(XIN = 32.768 kHz) reject both 50 and 60 Hz (±3 Hz) line
interference simultaneously.
Low power, single conversion settling time, programma-
ble output rates, and the ability to handle negative input
signals make these single supply products ideal solu-
tions for isolated and non-isolated applications.
