LTC Intros LTC2220 Family of Analog-to-Digital Converters

September 20, 2004 by Jeff Shepard

Linear Technology Corp. (LTC, Milpitas, CA) introduced a new family of high-speed analog-to-digital converters (ADCs) that combine ac performance with low power, making them suitable for a range of wireless and cable communications systems. The LTC2220 family includes ADCs ranging from 10 Msps up to 170 Msps at 12-bit and 10-bit resolution, as well as 14-bit converters up to 80 Msps.

The LTC2220 family of 3.3 V converters features low power without sacrificing ac performance, and are well suited for communications applications such as WCDMA cellular base station transceivers, digital pre-distortion power amplifier linearization, and cable modem termination systems.

The entire LTC2220 ADC family, which includes 24 devices, will be introduced by the fourth calendar quarter. The new ADC family features pin-compatibility, allowing easy migration from 10-bit to 12-bits or 14-bits, or to different sample rates. In addition to the LTC2224, Linear Technology is also announcing five additional low-power ADCs - the LTC2222, LTC2223, LTC2234, LTC2232 and LTC2233. All are now in production and are packaged in 7 mm x 7 mm QFN packages.
