The LTC6227 are very fast, low noise rail-to-rail output, unity gain stable single/dual op amps, with a gainbandwidth product of 420MHz and a slew rate of 180V/?s. The low input referred voltage noise of only 1nV/?Hz and low distortion of less than ?90dBC for 4VP-P signals at 1MHz makes them ideal for applications that require high dynamic range and deal with very fast signals, such as driving A/D converters.The combination of low offset, low offset drift, high gain (139dB) and high CMRR (114dB) make these excellent devices for high dynamic range applications.The LTC6226 family maintains excellent performance for supply voltages of 2.8V to 11.75V and the devices are fully specified at supplies of 3V, 5V and 10V (?5V).With an input range extending to the negative rail and rail-to-rail output stage, the operational amplifier can accommodate wide swinging signals, and true single supply operation.For space constrained applications, the amplifiers come in 2mm ? 2mm DFN (single) and 3mm ? 3mm DFN (dual) packages. The devices are also available in 8-lead SOIC,TSOT-23 and MS8E.These amplifiers can be used as replacements for many high speed op amps to improve speed, noise and dynamic range.?Applications Optical Electronics: Fast AC-Coupled Transimpedance Amplifiers Driving High Dynamic Range A/D Converters Active Filters Video Amplifiers Low Voltage Low Distortion Amplification

The SSM2375 is a fully integrated, high efficiency, Class-D audioamplifier. It is designed to maximize performance for mobilephone applications. The application circuit requires a minimumof external components and operates from a single 2.5 V to 5.5 Vsupply. It is capable of delivering 3 W of continuous output powerwith 100 dB.Spread-spectrum pulse density modulation (PDM) is used toprovide lower EMI-radiated emissions compared with otherClass-D architectures. The inherent randomized nature ofspread-spectrum PDM eliminates the clock intermodulation(beating effect) of several amplifiers in close proximity.The SSM2375 includes an optional modulation select pin(ultralow EMI emissions mode) that significantly reduces theradiated emissions at the Class-D outputs, particularly above100 MHz. In ultralow EMI emissions mode, the SSM2375can pass FCC Class B radiated emission testing with 50 cm,unshielded speaker cable without any external filtering.The device also includes a highly flexible gain select pin thatallows the user to select a gain of 0 dB, 3 dB, 6 dB, 9 dB, or12 dB. The gain selection feature improves gain matchingbetween multiple SSM2375 devices within a single applicationas compared to using external resistors to set the gain.The SSM2375 has a micropower shutdown mode with a typicalshutdown current of 20 nA. Shutdown is enabled by applyinga logic low to the SD pin.The device also includes pop-and-click suppression circuitry.This suppression circuitry minimizes voltage glitches at theoutput during turn-on and turn-off, reducing audible noiseon activation and deactivation.Other features that simplify system-level integration of theSSM2375 include input low-pass filtering to suppress out-of-bandDAC noise interference to the PDM modulator and fixed-inputimpedance to simplify component selection across multipleplatform production builds.The SSM2375 is specified over the industrial temperature rangeof ?40?C to +85?C. It has built-in thermal shutdown and outputshort-circuit protection. It is available in a halide-free, 9-ball,1.5 mm ? 1.5 mm wafer level chip scale package (WLCSP).Applications Mobile phones MP3 players Portable electronics

The SSM4321 is a fully integrated, high efficiency, Class-Daudio amplifier with digitized output of output voltage, outputcurrent, and the PVDD supply voltage. It is designed to maximize performance for mobile phone applications. The application circuit requires a minimum of external components and operates from a 2.5 V to 5.5 V supply for the amplifier and a 1.42 V to 3.6 V supply for input/output. The SSM4321 is capable of delivering 2.2 W of continuous output power with 100 dB.The SSM4321 includes circuitry to sense output current, output voltage, and the PVDD supply voltage. Current sense is performedusing an external sense resistor that is connected between anoutput pin and the load. The output current and voltage are sentto ADCs with 16-bit resolution; the PVDD supply voltage is sent to an ADC with 8-bit resolution.The outputs of these ADCs are available on the TDM or I2S output serial port. The SLOT pin is used to determine which of four possible output slots is used on the TDM interface. A stereo I2S interface can be selected by reversing the pin connections forBCLK and FSYNC. Also, a direct PDM bit stream of voltage andcurrent data can be selected via the SLOT pin.Spread-spectrum pulse density modulation (PDM) is used to provide lower EMI-radiated emissions compared with other Class-D architectures. The inherent randomized nature of spread-spectrum PDM eliminates the clock intermodulation (beating effect) of several amplifiers in close proximity.The SSM4321 produces ultralow EMI emissions that significantlyreduce the radiated emissions at the Class-D outputs, particularly above 100 MHz. The ultralow EMI emissions of the SSM4321 arealso helpful for antenna and RF sensitivity problems.The device includes a highly flexible gain select pin that requiresonly one series resistor to select a gain setting of 0 dB, 3 dB, 6 dB, 9 dB, or 12 dB. Input impedance is fixed at 80 k?, independent of the selected gain.The SSM4321 has a shutdown mode with a typical shutdowncurrent of <1 ?A. Shutdown is enabled by removing the BCLK input. A clock must be present on the BCLK pin for the part to operate. The device also includes pop-and-click suppression circuitry, which minimizes voltage glitches at the output during turn-on and turn-off, reducing audible noise on activation and deactivation.The SSM4321 is specified over the industrial temperature rangeof ?40?C to +85?C. It has built-in thermal shutdown and output short-circuit protection. It is available in a halide-free, 16-ball, 0.4 mm pitch, 1.74 mm ? 1.74 mm wafer level chip scale package (WLCSP).Applications Mobile phones MP3 players Portable electronics
