Linear Technology Corp. (LTC, Milpitas, CA) announced its new LTC2220 family of analog-to-digital converters (ADCs), which achieve low power consumption with ac performance. At 230 mW, in a 5 mm x 5 mm QFN package, the LTC2249 is only half the power of its nearest competitor at this speed, has a small package and board size, and achieves over 73 dB SNR up to 100 MHz input.
The LTC2249 is one of 13 new ADCs introduced by LTC, as part of its expanding family of low-power, high-speed ADCs, which range from 10 Msps to 170 Msps at 12-bit and 10-bit resolution, as well as 14-bit converters up to 80 Msps. The low-power ADCs excel at undersampling, making them well suited for communications applications such as WCDMA cellular base station transceivers, digital predistortion power amplifier linearization, and cable modem termination systems.
All 13 ADCs are now in production and are packaged in 5 mm x 5 mm QFN packages. The LTC2220 family is available now . Pricing ranges from $3.50 to $33.92.
