LTC6911CMS-1#PBF

LTC®6911 is a family of low noise digitally programmable gain amplifiers (PGAs) that are easy to use and occupy very little PC board space. The LTC6911 family consists of two matched inverting amplifiers with rail-to-rail outputs. When operated with unity gain, they will also process rail-to-rail input signals. A half-supply reference generated internally at the AGND pin supports single power supply applications. Typical applications includes data acquisition systems, dynamic gain changing, automatic ranging circuits and automatic gain control.

• 3bit digital gain control: (inverting gains of 0, 1, 2, 5, 10, 20, 50 and 100V/V)
• Single or dual supply: 2.7V to 10.5V total
• Two matched programmable gain amplifiers
• Channel-to-channel gain matching of 0.1dB (max) at VS = 2.7V, gain = 1, RL = 10K
• Rail-to-rail input range, rail-to-rail output swing
• 11MHz gain bandwidth product at gain = 100, fIN = 200KHz
• 80dB typ power supply rejection ratio (PSRR), -120dB signal attenuation at gain=0 setting, f=20KHz
• 12V/µs typ slew rate at VS = 5V, VOUTA = VOUTB = 1.1V to 3.9V
• 10 lead MSOP package
• Operating temperature range from -40°C to 85°C
