Übersicht
Description
- Resolution: 12 bits
- Channels: 16 single-ended or 8 pseudo-differential inputs
- Throughput: Up to 1 MSPS (Mega Samples Per Second)
- Interface: SPI/QSPI/MICROWIRE compatible
- Power Supply: 2.7V to 5.25V, with low power consumption (~3.5mW at 1MSPS, 3V)
- Package: TSSOP-28 (BRUZ), REEL7 denotes tape & reel packaging
Ideal for industrial control, medical instruments, and data acquisition where high-speed, multi-channel ADC performance is needed. Includes an on-chip reference (2.5V) and temperature sensor.
Equivalent
- AD7685 (16-bit, 250 kSPS, lower speed)
- AD7980 (16-bit, 1 MSPS, similar performance)
- LTC1867 (16-bit, 1 MSPS, from Linear Tech)
- MAX11156 (16-bit, 1 MSPS, from Maxim Integrated)
These alternatives offer comparable resolution and speed but may differ in features like power consumption, interface, or package options. Always check datasheets for exact compatibility.
