Dual-Channel Diff Amps Deliver Fast Measurements

The 10-MHz AD8270 and 12-MHz AD8273 dual-channel difference amplifiers are said to be three times faster than comparable devices on the market. The AD8270 features a 30 V/µs slew rate, while the AD8273 specifies 25 V/µs. Reportedly, both devices exhibit high dc precision, best-in-class SNRs, and an 86-dB common mode rejection that is 12 dB higher than similar devices. The AD8270 is available in a 4 mm x 4 mm package, and the AD8273 comes in a 54-mm square package. Additionally, both integrate gain-setting resistors. Prices for the AD8270 and AD8273 are $1.99 and $1.65 each/1,000, respectively. ANALOG DEVICES INC., Norwood, MA. (800) 262-5643.
