Linear Technology LTC2258CUJ-12#PBF
- Part Number:
- LTC2258CUJ-12#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3009814-LTC2258CUJ-12#PBF
- Description:
- IC ADC 12BIT 65MSPS 1.8V 40-QFN
- Datasheet:
- LTC2258CUJ-12#PBF
Description
The LTC2258-12/LTC2257-12/LTC2256-12 are 12-bit, 65/40/25Msps ultralow power 1.8V ADCs designed for digitizing high-frequency, wide dynamic range signals. They are ideal for demanding communications applications with AC performance that includes 71.1dB SNR and 88dB spurious free dynamic range (SFDR). Ultralow jitter of 0.17pSRMS allows undersampling of IF frequencies with excellent noise performance.
DC specs include 0.3LSB INL (typical), 0.1LSB DNL (typical) and no missing codes over temperature. The transition noise is a low 0.3LSBRMS. The digital outputs can be either full rate CMOS, double data rate CMOS, or double data rate LVDS. A separate output power supply allows the CMOS output swing to range from 1.2V to 1.8V.
The ENC and ENC inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
Features
Low Power: 79mW/47mW/34mW
Single 1.8V Supply
