Description
- Resolution: 12 bits
- Channels: 16 single-ended or 8 pseudo-differential
- Supply Voltage: 2.7V to 5.25V
- Power Consumption: Low power (3.5 mW at 1 MSPS, 5V)
- Interface: SPI/QSPI/MICROWIRE-compatible
The ADC includes an on-chip track-and-hold, a 2.5V internal reference, and supports ±VREF input ranges (0V to VREF). It’s ideal for multiplexed data acquisition, industrial control, and medical systems.
Packaged in a TSSOP-28, the AD7490BRUZ offers flexible power-down modes for power-sensitive applications. Its fast conversion time (1 µs) and low noise make it suitable for precision measurements.
For detailed specs, refer to the datasheet on Analog Devices' website.
Equivalent
- AD7685: 16-bit, 250 kSPS SAR ADC (higher resolution, lower speed).
- AD7980: 16-bit, 1 MSPS SAR ADC (higher resolution, similar speed).
- LTC1867: 16-bit, 250 kSPS SAR ADC (higher resolution, lower speed).
- MAX11156: 12-bit, 1 MSPS SAR ADC (similar specs, different package).
