Product Overview
The CS5533‑ASZR is a 16‑bit 4‑channel Delta‑Sigma ADC from Cirrus Logic. It features integrated low‑noise PGA, 4th‑order modulator and configurable digital filter. It directly reads low‑level sensor signals without external conditioning circuits. CS5534‑ASZR is the 24‑bit counterpart. Packaged in 24‑SSOP tape‑reel, it suits industrial precision measurement applications.
Core Advantages
Ultra‑Low‑Noise PGA
Programmable gain 1x‑64x for microvolt‑level sensor signal input.
4‑Channel Multiplexer
Supports differential/single‑ended input with low cross‑talk.
Configurable Digital Filter
Adjustable output rate with selectable 50Hz/60Hz line‑noise rejection.
3‑Wire SPI Interface
Simple 3‑wire serial communication with microcontrollers.

Frequently Asked Questions
Q1: What ADC architecture does CS5533‑ASZR adopt?
A: It uses Delta‑Sigma architecture with integrated low‑noise PGA and digital filter for precision measurement.
Q2: What does the “R” suffix mean?
A: “R” = Tape & Reel for SMT assembly. Without R is tube packaging for small‑batch use.
Q3: Can it connect directly to strain‑gauge sensors?
A: Yes. Built‑in PGA up to 64x gain supports microvolt‑level signals without external amplifiers.
Q4: What are the differences among CS5531/32/33/34 series?
A: CS5531/33 are 16‑bit; CS5532/34 are 24‑bit. CS5531/32 are 2‑channel, CS5533/34 are 4‑channel, all share same 24‑SSOP package.
Q5: Can CS5533‑ASZR work with single‑supply power?
A: Yes. Supports +5V single supply, or ±2.5V / ±3V dual‑supply operation.
Q6: Are there pin‑compatible cross‑brand alternatives?
A: No direct pin‑to‑pin drop‑in replacement. TI ADS1248 is a functional alternative, requiring firmware modification.
Q7: Does it reject 50Hz/60Hz mains noise?
A: Yes, built‑in filter supports selectable 50Hz or 60Hz notch rejection for industrial environments.
Q8: How to get datasheet or bulk quotation?
A: Submit inquiry form for datasheet, stock check and volume pricing.
