Linear Technology LTC2291IUP#PBF
- Part Number:
- LTC2291IUP#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3017113-LTC2291IUP#PBF
- Description:
- IC ADC DUAL 12BIT 25MSPS 64QFN
- Datasheet:
- LTC2291IUP#PBF
Description
The LTC2293/LTC2292/LTC2291 are dual 12-bit, 65Msps/40Msps/25Msps, low-power 3V A/D converters designed for digitizing high-frequency, wide dynamic range signals. They are ideal for demanding imaging and communications applications, offering excellent AC performance with 71.3dB SNR and 90dB SFDR for signals at the Nyquist frequency. DC specifications include 0.3LSB INL (typ), ±0.15LSB DNL (typ), and no missing codes over temperature. The transition noise is a low 0.25LSBRMS.
A single 3V supply enables low power operation, while a separate output supply allows the outputs to drive 0.5V to 3.6V logic. An optional multiplexer allows both channels to share a digital output bus.
A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer ensures high performance at full speed for a wide range of clock duty cycles.
