Linear Technology LTC2321IUFD-12#PBF
- Part Number:
- LTC2321IUFD-12#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3010857-LTC2321IUFD-12#PBF
- Description:
- IC ADC 12BIT 2MSPS 28QFM
- Datasheet:
- LTC2321IUFD-12#PBF
Description
The LTC2321-12 is a dual, 12-bit sign, 2Msps differential input ADC with a wide input common mode range. It operates from a single 3.3V or 5V supply and has an 8Vp.p differential input range. The LTC2321-12 achieves ±0.5LSB INL typical, no missing codes at 12 bits, and 73dB SNR. It has an onboard low drift (20ppm/°C max) 2.048V or 4.096V internal reference and a high speed SPI-compatible serial interface that supports CMOS or LVDS. The LTC2321-12 dissipates only 30mW per channel and offers nap and sleep modes to reduce power consumption to 5μW during inactive periods.
