General Description
The CS5521/22/23/24/28 are highly integrated
ΔΣ ana-
log-to-digital converters (ADCs) which use charge-
balance techniques to achieve 16-bit (CS5521/23) and
24-bit (CS5522/24/28) performance. The ADCs come as
either
two-channel
(CS5521/22),
four-channel
(CS5523/24), or eight-channel (CS5528) devices and
include a low-input-current, chopper-stabilized instru-
mentation amplifier. To permit selectable input spans of
25 mV, 55 mV, 100 mV, 1 V, 2.5 V, and 5 V, the ADCs
include a PGA (programmable gain amplifier). To ac-
commodate ground-based thermocouple applications,
the devices include a charge pump drive which provides
a negative bias voltage to the on-chip amplifiers.
These devices also include a fourth-order
ΔΣ modulator
followed by a digital filter which provides eight selectable
output word rates. The digital filters are designed to settle
to full accuracy within one conversion cycle and when
operated at word rates below 30 Sps, they reject both
50 Hz and 60 Hz interference.
These single-supply products are ideal solutions for
measuring isolated and non-isolated, low-level signals in
process control applications.
