AD7194BCPZ-REEL7

• Product introduction

AD7194BCPZ-REEL7 8-channel, 4.8 kHz, ultralow noise, 24-bit, sigma-delta ADC with internal PGA

The AD7194 is a low noise, complete analog front end for high precision measurement applications. It integrates a low noise, 24-bit Σ-Δ typeAnalog-to-digital converters(ADC)。 The on-chip low noise gain stage means that small signals can be input directly. The device can be configured as 8 differential inputs or 16 pseudo differential inputs. The on-chip 4.92 MHz clock can be used as a clock source for the ADC; Alternatively, an external clock or crystal oscillator can be used. The output data rate of the device can vary from 4.7 Hz to 4.8 kHz.

The device features a very flexible digital filter, including a fast settling option. Variables such as output data rate and settling time depend on the option selected. For applications that require all conversions to be built, the AD7194 features zero latency.

The device operates from a supply voltage of 3 V to 5.25 V, consumes 4.65 mA, and is available in a 32-pin LFCSP package.
