CS5524 General Description

The CS5521/22/23/24/28 are highly integrated Analog- to-Digital Converters (ADCs) which use chargebalance
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 instrumentation 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 accommodate 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 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 Hz, they reject both 50 and 60 Hz interference.

These single supply products are ideal solutions for measuring isolated and non-isolated, low-level signals in process control applications.

Notes: 21. No pin should go more negative than NBV - 0.3 V.
           22. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pins.
           23. Transient current of up to 100 mA will not cause SCR latch-up. Maximum input current for a power
                 supply pin is ±50 mA.
           24. Total power dissipation, including all input currents and output currents.

WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation
                  is not guaranteed at these extremes.
