MILPITAS, CA – September 8, 2011 – Linear Technology introduces the LTC6360, a very low noise, high speed amplifier that can drive to 0V while maintaining high linearity on a single +5V supply. The LTC6360’s integrated ultralow noise charge pump provides an internal negative rail, eliminating the need for a negative supply. Compared to typical rail-to-rail output single-supply amplifiers that can only swing to within a few hundred millivolts of ground, the LTC6360 provides improved linearity and dynamic range in applications that benefit from a true zero output swing.
The LTC6360 achieves outstanding precision and is ideal for driving 16- and 18-bit SAR ADCs (successive approximation register analog-to-digital converters). Input offset voltage is less than 250µV max, and noise is only 2.3nV/√Hz, providing excellent dynamic range. The device settles to 16-bits in 150ns, and achieves a closed loop
-3dB bandwidth of 250MHz. Harmonic distortion (HD2/HD3) is -103dBc/-109dBc at fIN = 40kHz. The LTC6360 is unity gain stable, allowing it to be used as a buffer to achieve the lowest output noise. The output is designed to drive a series 10Ω resistor and 330pF capacitor filter network, although larger load capacitances can be driven.
The LTC6360 is available in MSOP and 3mm x 3mm DFN 8-pin packages, and is fully specified over the commercial (0°C to 70°C), industrial (-40°C to 85°C), and extended (-40°C to 125°C) temperature ranges. Prices start at $2.19 each in 1,000 piece quantities. For more information, visit www.linear.com/product/LTC6360.
