LTC2983 20 sensor chip!

Just saw this in the latest digikey promo email. It's basically around the same cost as 4 x TC amps but has 20 inputs!

LTC2983 Multi-Sensor, High-Accuracy, Digital Temperature Measurement System

• 20 flexible inputs allow multiple sensor types
• Automatic thermocouple cold junction compensation
• Standard and user-programmable coefficients for linearizing thermocouples, RTDs and thermistors

Configuration and output is done over SPI

Wow that is neat as heck! $38 in quantity one though, golly. Also a 44 pin TQFP I can't imagine routing that sucker, but I suck at routing.
