Price Comparison for MAX97220BETE+T
Series Information for MAX97220BETE+T - Maxim Integrated


The MAX97220_ is a differential input DirectDrive® line driver/headphone amplifier. This device is capable of driving line level loads with 3VRMS into 1kI with a 5V supply and 2VRMS into 600I loads from a 3.3V supply. A headphone load is capable of being driven with 125mW into 32I with a 5V supply. The IC is offered with an inter- nally fixed 6dB gain or an externally set gain through external resistors. The external gain setting nodes can also be used to configure filters for set-top box applica- tions. The IC has exceptional THD+N over the full audio bandwidth. Two versions of the IC are available with different turn- on times (tON). The A, C, and E versions for headphone applications feature a tON of 5.5ms while the B and D versions, intended for set-top-box applications, feature a 130ms tON. An on-chip charge pump inverts the power- supply input, creating a negative rail. The output stage of the amplifier is powered between the positive input sup- ply and the output of the charge pump. The bipolar sup- plies bias the output about ground, eliminating the need for large, distortion-introducing output coupling capaci- tors. The IC powers on and off without clicks or pops. The IC is available in a 3mm x 3mm x 0.8mm, 16-pin TQFN and is specified over the extended -40NC to +85NC temperature range.
