- Part Number:
- AD9248BSTZ-20
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3012532-AD9248BSTZ-20
- Description:
- IC ADC 14BIT DUAL 20MSPS 64-LQFP
- Datasheet:
- AD9248BSTZ-20
Description
The AD9248 is a dual, 14-bit, 20 MSPS/40 MSPS/65 MSPS analog-to-digital converter (ADC) with integrated dual 14-bit ADCs. It operates on a single 3 V supply (2.7 V to 3.6 V) and features a differential input with 500 MHz, 3 dB bandwidth. The AD9248 uses a multistage differential pipelined architecture with output error correction logic to provide 14-bit accuracy and guarantee no missing codes over the full operating temperature range at up to 65 MSPS data rates. The wide bandwidth, differential SHA allows for a variety of user-selectable input ranges and offsets, including single-ended applications.
Features
Pin-compatible with the AD9238, 12-bit 20 MSPS/40 MSPS/65 MSPS ADC
Speed grade options of 20 MSPS, 40 MSPS, and 65 MSPS
Low power consumption: AD9248-65: 65 MSPS = 600 mW, AD9248-40: 40 MSPS = 330 mW, and AD9248-20: 20 MSPS = 180 mW
Typical channel isolation of 85 dB @fox 10 MHz
Clock duty cycle stabilizer (AD9248-20/AD9248-40/AD9248-65) maintains performance over a wide range of clock duty cycles
Multiplexed data output option enables single-port operation from either Data Port A or Data Port B
Applications
Ultrasound equipment
Direct conversion or IF sampling receivers
WB-CDMA, CDMA2000, WIMAX
Battery-powered instruments
Hand-held scopemeters
Low cost digital oscilloscopes
