19-2136; Rev 1; 9/01 SC70/SOT23-8, 50mA IOUT, Rail-to-Rail I/O Op Amps with Shutdown/Mute General Description The MAX4335–MAX4338 op amps deliver 40mW per channel into 32Ω from ultra-small SC70/SOT23 packages making them ideal for mono/stereo headphone drivers in portable applications. These amplifiers have a 5MHz gain-bandwidth product and are guaranteed to deliver 50mA of output current while operating from a single supply of 2.7V to 5.5V. The MAX4336 and the MAX4338 have a shutdown/mute mode.

19-2136; Rev 1; 9/01 SC70/SOT23-8, 50mA IOUT, Rail-to-Rail I/O Op Amps with Shutdown/Mute General Description The MAX4335–MAX4338 op amps deliver 40mW per channel into 32Ω from ultra-small SC70/SOT23 packages making them ideal for mono/stereo headphone drivers in portable applications. These amplifiers have a 5MHz gain-bandwidth product and are guaranteed to deliver 50mA of output current while operating from a single supply of 2.7V to 5.5V. The MAX4336 and the MAX4338 have a shutdown/mute mode that reduces the supply current to 0.04µA per amplifier and places the outputs in a high-impedance state. The MAX4335–MAX4338 have 90dB power-supply rejection ratio (PSRR), eliminating the need for costly pre-regulation in most audio applications. Both the input voltage range and the output voltage swing include both supply rails, maximizing dynamic range. The MAX4335/MAX4336 single amplifiers are available in ultra-small 6-pin SC70 packages. The MAX4337/ MAX4338 dual amplifiers are available in an 8-pin SOT23 and a 10-pin µMAX package, respectively. All devices are specified from -40°C to +85°C. o 50mA Output Drive Capability o Low 0.003% THD (20kHz into 10kΩ) o Rail-to-Rail® Inputs and Outputs o 2.7V to 5.5V Single-Supply Operation o 5MHz Gain-Bandwidth Product o 95dB Large-Signal Voltage Gain o 90dB Power-Supply Rejection Ratio o No Phase Reversal for Overdrive Inputs o Ultra-Low Power Shutdown/Mute Mode Reduces Supply Current to 0.04µA Places Output in High-Impedance State o Thermal Overload Protection Features MAX4335–MAX4338 Ordering Information PART MAX4335EXT-T MAX4336EXT-T MAX4337EKA-T MAX4337EUA MAX4338EUB TEMP RANGE -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C PINPACKAGE 6 SC70-6 6 SC70-6 8 SOT23-8 8 µMAX 10 µMAX TOP MARK AAX AAW AAIK — — ________________________Applications 32Ω Headphone Drivers Portable/Battery-Powered Instruments Wireless PA Control Hands-Free Car Phones Transformer/Line Drivers DAC/ADC Buffers Pin Configurations appear at end of data sheet.
