Datasheet
The AD7734 is a high precision, high throughput analog front end. It has a true 16-bit p-p resolution with a total conversion time of 500 µs (2 kHz channel switching), making it ideally suited for high resolution multiplexing applications. The part can be configured via a simple digital interface, which allows users to balance the noise performance against data throughput up to a 15.4 kHz. The analog front end features four single-ended input channels with unipolar or true bipolar input ranges to ±10 V while operating from a single +5 V analog supply. The part has an overrange and underrange detection capability and accepts an analog input overvoltage protection.
Datasheet
The AD7734 is a high precision, high throughput analog front end from TI. It features 24 bits no missing codes, ±0.0025% nonlinearity, 18-bit p-p resolution (21 bits effective) at 500 Hz, 16-bit p-p resolution (19 bits effective) at 2 kHz, and 14-bit p-p resolution (18 bits effective) at 15 kHz. The device also integrates on-chip per channel system calibration, supports 4 single-ended analog inputs, and has ±10 V input ranges. It can be configured via a 3-wire serial interface SPI™, QSPI™, MICROWIRE™, and DSP compatible Schmitt trigger on logic inputs. The AD7734 operates with a single +5 V analog supply and 3 V or 5 V digital supply. It comes in a 28-lead TSSOP package. AD7734 is suitable for PLCs/DCS, multiplexing applications, process control, and industrial instrumentation.
