ADR821

ANALOG DEVICE

Analog Device ADR821 2.5V Low Power, Precision Reference And Operational Amplifier Simple Type: Amplifier The ADR821 offers a combination of precision voltage reference and op amp in a 10-lead mini small outline package (MSOP). The reference and the op amp can be operated independently, offering the user a range of flexibility for arranging the combination. Featuring a combined operating current of less than 400 µA and 15 ppm/°C on the reference, the ADR821 is ideally suited for applications requiring precision and low power. Available with the reference at 1.25 V and at 2.5 V, the ADR821 also comes in two grades. The reference on the A grade offers 30 ppm/°C temperature drift performance and ±0.4% initial accuracy. The B grade provides tighter temperature drift performance of 15 ppm/°C and only ±0.2% initial accuracy. All versions operate from -40°C to +125°C. Download the datasheet (PDF)

AD9643

ANALOG DEVICE

Analog Device AD9643 14-Bit 170/210/250 MSPS 1.8V Dual Analog-to-Digital Converter Simple Type: Analog I/O Module The AD9643 is a dual 14-bit, analog-to-digital converter (ADC) with sampling speeds up to 250 MSPS. The AD9643 is designed to support communications applications where low cost, small size, wide bandwidth and versatility are desired. The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance. Download the datasheet (PDF)
