AD7995ARJZ-0RL

4通道， 12 /10位/ 8位ADC， I2C兼容接口采用8引脚SOT -23 4-Channel, 12-/10-/8-Bit ADC with I2C-Compatible Interface in 8-Lead SOT-23

GENERAL DESCRIPTION

The AD7991/AD7995/AD7999 are 12-/10-/8-bit, low power, successive approximation ADCs with an I2C®-compatible interface. Each part operates from a single 2.7 V to 5.5 V power supply and features a 1 μs conversion time. The track-and-hold amplifier allows each part to handle input frequencies of up to 14 MHz, and a multiplexer allows taking samples from four channels.
