The device is unity-gain stable to 3.5MHz and operates from a single 2.3V to 5.5V supply. The MAX4369 is guaranteed to source and sink up to 87mA with a 5V supply. The MAX4369 is capable of delivering 120mW of continuous average power to a 16Ω load, or 75mW to a 32Ω load with 1% total harmonic distortion plus noise (THD + N), making the device ideal for portable audio applications. The MAX4369 is specified over the extended temperature range (-40°C to +85°C) and is available in a tiny (1.5mm x 1.5mm) 9-bump UCSP.

Figure 1 shows the output voltage swing of the MAX4369 configured with AV = 2V/V. Driving Capacitive Loads Driving a capacitive load can cause instability in many op amps. The MAX4369 is unity-gain stable for a range of capacitive loads to 200pF. Figure 2 shows the response of the MAX4369 with an excessive capacitive load. Adding a series resistor between the output and the output capacitor improves the circuit’s response by isolating the load capacitance from the op amp’s output. VCC = 5V RL = 10kΩ Under normal operating conditions, linear power amplifiers like the MAX4369 can dissipate a significant amount of power. The maximum power dissipation of the UCSP package is given in the Absolute Maximum Ratings section under Continuous Power Dissipation or can be calculated by the following equation: PDISS(MAX) = TJ(MAX) − TA θJA where TJ(MAX) is +150°C and θJA is the reciprocal of the derating factor in °C/W as specified in the Absolute Maximum Ratings. For example, θJA of a UCSP package is 211°C/W. If the power dissipation exceeds the maximum allowed for a given package, either reduce VCC, increase load impedance, decrease the ambient temperature or add heat sinking to the device. Large output, supply, and ground traces improve the maximum power dissipation in the package. Thermal overload protection limits total power dissipation in the MAX4369. When the junction temperature exceeds +165°C, the thermal protection circuitry disables the amplifier output stage. The amplifiers are enabled once the junction temperature cools by 10°C. This results in a pulsing output under continuous thermal overload conditions. 5V IN_ 100mV/div OUT_ 200mV/div OUT_ GND 4µs/div 400µs/div AV = 2V/V VCC = 5V CLOAD = 1nF Figure 1.

Differential Input/Differential Output Audio Amplifier Supply Bypassing Proper supply bypassing ensures low-noise, low-distortion performance. Place a 0.1µF ceramic capacitor in parallel with a 10µF capacitor from VCC to GND. Locate the bypass capacitors as close to the device as possible. Layout Considerations Good layout improves performance by decreasing the amount of stray capacitance and noise at the amplifier’s inputs and outputs. Decrease stray capacitance by minimizing PC board trace lengths, using surfacemount components and placing external components as close to the device as possible. UCSP Considerations For general UCSP information and PC layout considerations, please refer to the Maxim Application Note: Wafer-Level Ultra-Chip-Scale Package. Audio Applications Single-Ended Stereo Amplifier The high-output-current drive makes the MAX4369 ideal for use as a stereo audio amplifier (see Typical Application Circuit/Functional Diagram). In this configuration, the MAX4369 can deliver 120mW per channel into 16Ω with less than 1% THD + N. The input capacitors (CIN) block the DC component of the incoming 8 audio signal from the MAX4369. See the Input Capacitor section for selecting the value of CIN. The output capacitors (COUT) serve to block the DC bias of the MAX4369 from the speaker load. See the Output Capacitor section for selecting the value of COUT. Set the DC bias (typically VCC/2) by the resistive voltage-divider formed by R1 and R2. Ensure that the DC-bias level gives the incoming audio signal the maximum amount of headroom. COUT can be eliminated by operating the MAX4369 from a dual supply (±1.15V to ±2.5V) and setting the DC bias to 0. Differential Input/Differential Output Audio Amplifier The MAX4369 can be used as a differential input/differential output (BTL) amplifier (Figure 3). This configuration offers good CMRR, improved low-frequency PSRR, no large output-coupling capacitors compared to a single-ended amplifier. Resistors RINB and RFB configure the second amplifier as an inverting unity-gain follower. Connect the noninverting input of the second amplifier to a bias voltage, typically VCC/2. Resistors RIN and RF set the differential gain of the device as follows: VOUT(DIFF) VIN(DIFF) = RF RIN _______________________________________________________________________________________ Dual, Rail-to-Rail, High-Output-Drive Op Amp in UCSP TIP (LEFT) RING (RIGHT) The MAX4369 can drive a stereo headphone when configured as a single-ended stereo amplifier. Typical 3wire headphone plugs consist of a tip, ring, and sleeve. The tip and ring are the signal carriers while the sleeve is the ground connection (Figure 4). Figure 5 shows the MAX4369 configured to drive a set of headphones. OUTB is coupled to the ring and OUTA is coupled to the tip, delivering the signal to the headphone. Capacitor Selection Input Capacitor The input capacitor (CIN), in conjunction with RIN, forms a high-pass filter that removes the DC bias from an incoming signal (see the Typical Application Circuit/ Functional Diagram). The AC-coupling capacitor allows the amplifier to bias the signal to an optimum DC level. Assuming zero-source impedance, the -3dB point of the high-pass filter is given by: SLEEVE (GND) f −3dB = 1 2πRINCIN Choose CIN such that f-3dB is well below the lowest frequency of interest. Setting f-3dB too high affects the low-frequency response of the amplifier. Use capacitors whose dielectrics have low-voltage coefficients, Figure 4.

Stereo Headphone Driver _______________________________________________________________________________________ 9 MAX4369 Headphone Driver The capacitors (CF) are necessary to maintain stability. The amplifier has two feedback paths, one from OUTA to INA- and the other from OUTB to INA+. At high frequencies, the second amplifier in the OUTB to INA+ feedback path introduces excessive phase shift. Compensate this phase shift by adding a capacitor from INA+ to GND. This suppresses the gain of the device at high frequencies, maintaining stability. Placing an identical-valued capacitor from INA- to OUTA improves overall performance. Proper matching of the RF and RIN components is essential for optimum performance. A resistor pack offers a cost-effective solution for these matched components. MAX4369 Dual, Rail-to-Rail, High-Output-Drive Op Amp in UCSP such as tantalum or aluminum electrolytic. Capacitors with high-voltage coefficients, such as certain ceramics, can result in an increase in distortion at low frequencies. Other considerations when designing the input filter include the constraints of the overall system, the actual frequency band of interest and click-and-pop suppression. Although high-fidelity audio calls for a flat gain response between 20Hz and 20kHz, portable voicereproduction devices such as cellular phones and walkie-talkies need only concentrate on the frequency range of the spoken human voice (typically 300Hz to 3.5kHz). In addition, speakers used in portable devices typically have a poor response below 150Hz. Taking these two factors into consideration, the input filter might not need to be designed for a 20Hz to 20kHz response, saving both board space and cost due to the use of smaller capacitors. Output-Coupling Capacitor The MAX4369 requires an output-coupling capacitor when configured as a single-ended amplifier. The output capacitor blocks the DC component of the amplifier output, preventing DC current flowing to the load. The output capacitor and the load impedance form a highpass filter with the -3dB point determined by: f −3dB = 1 2πRLCOUT Bump Configuration TOP VIEW (BUMP SIDE DOWN) 1 2 3 INA- OUTA INA+ A B MAX4369 GND VCC C INB- OUTB INB+ UCSP UCSP PKG CODE: B9-2 B2 POSITION IS NOT POPULATED Chip Information TRANSISTOR COUNT: 669 PROCESS: BiPOLAR As with the input capacitor, choose COUT such that f-3dB is well below the lowest frequency of interest. Setting f-3dB too high affects the low-frequency response of the amplifier. In addition to frequency band considerations, the load impedance is another concern when choosing COUT. Load impedance can vary, changing the -3dB point of the output filter. A lower impedance increases the corner frequency, degrading low-frequency response. Select COUT such that the worst-case load/COUT combination yields an adequate response. 10 ______________________________________________________________________________________ Dual, Rail-to-Rail, High-Output-Drive Op Amp in UCSP Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
