MAX4238/MAX4239 General Description The MAX4238/MAX4239 are low-noise, low-drift, ultrahigh precision amplifiers that offer near-zero DC offset and drift through the use of patented autocorrelating zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. Both devices feature rail-to-rail outputs, operate from a single 2.7V to 5.5V supply, and consume only 600µA. An activelow shutdown mode decreases supply current to 0.1µA. The MAX4238 is unity-gain stable with a gain-bandwidth product of 1MHz, while the decompensated MAX4239 is stable with AV ≥ 10V/V and a GBWP of 6.5MHz. The MAX4238/MAX4239 are available in 8-pin narrow SO, 6-pin TDFN and SOT23 packages.

Not internally connected. — — — EP Detailed Description Exposed Pad (TDFN only). Connect EP to GND. The MAX4238/MAX4239 are high-precision amplifiers that have less than 2.5µV of input-referred offset and low 1/f noise. These characteristics are achieved through a patented autozeroing technique that samples and cancels the input offset and noise of the amplifier. The pseudorandom clock frequency varies from 10kHz to 15kHz, reducing intermodulation distortion present in chopper-stabilized amplifiers. www.maximintegrated.com To achieve very low offset, several sources of error common to autozero-type amplifiers need to be considered. The first contributor is the settling of the sampling capacitor. This type of error is independent of input-source impedance, or the size of the external gain-setting resistors. Maxim uses a patented design technique to avoid large changes in the voltage on the sampling capacitor to reduce settling time errors. The second error contributor, which is present in both autozero and chopper-type amplifiers, is the charge injection from the switches. The charge injection appears as current spikes at the input, and combined with the impedance seen at the amplifier’s input, contributes to input offset voltage. Minimize this feedthrough by reducing the size of the gain-setting resistors and the input-source impedance. A capacitor in parallel with the feedback resistor reduces the amount of clock feedthrough to the output by limiting the closed-loop bandwidth of the device. The design of the MAX4238/MAX4239 minimizes the effects of settling and charge injection to allow specification of an input offset voltage of 0.1µV (typ) and less than 2.5µV over temperature (-40°C to +85°C). 1/f Noise 1/f noise, inherent in all semiconductor devices, is inversely proportional to frequency. 1/f noise increases 3dB/octave and dominates amplifier noise at lower frequencies. This noise appears as a constantly changing voltage in series with any signal being measured. The MAX4238/MAX4239 treat 1/f noise as a slow varying offset error, inherently canceling the 1/f noise. Maxim Integrated │  8 MAX4238/MAX4239 TOP VIEW IN- Pin Configurations SHDN Autozeroing amplifiers typically require a substantial amount of time to recover from an output overload. This is due to the time it takes for the null amplifier to correct the main amplifier to a valid output. The MAX4238/MAX4239 require only 3.3ms to recover from an output overload (see Electrical Characteristics and Typical Operating Characteristics). VCC Output Overload Recovery Ultra-Low Offset/Drift, Low-Noise, Precision SOT23 Amplifiers 6 5 4 EP* MAX4238/ MAX4239 Shutdown The MAX4238/MAX4239 feature a low-power (0.1µA) shutdown mode. When SHDN is pulled low, the clock stops and the device output enters a high-impedance state. Connect SHDN to VCC for normal operation. Applications Information ADC Buffer Amplifier The low offset, fast settling time, and 1/f noise cancellation of the MAX4238/MAX4239 make these devices ideal for ADC buffers. The MAX4238/MAX4239 are well suited for low-speed, high-accuracy applications, such as strain gauges (see Typical Application Circuit). 2 3 GND IN+ TDFN (3mm x 3mm x 0.8mm) Minimum and Maximum Gain Configurations The MAX4238 is a unity-gain stable amplifier with a gain-bandwidth product (GBWP) of 1MHz. The MAX4239 is decompensated for a GBWP of 6.5MHz and is stable with a gain of 10V/V. Unlike conventional operational amplifiers, the MAX4238/MAX4239 have a maximum gain specification. To maintain stability, set the gain of the MAX4238 between AV = 1000V/V to 1V/V, and set the gain of the MAX4239 between AV = 6700V/V and 10V/V. 1 OUT + *CONNECT EP TO GND.

IN+ SO OUT 1 6 VCC GND 2 5 SHDN IN+ 3 4 IN- SOT23 Error Budget Example When using the MAX4238/MAX4239 as an ADC buffer, the temperature drift should be taken into account when determining the maximum input signal. With a typical offset drift of 10nV/°C, the drift over a 10°C range is 100nV. Setting this equal to 1/2LSB in a 16-bit system yields a full-scale range of 13mV. With a single 2.7V supply, an acceptable closed-loop gain is AV = 200. This provides sufficient gain while maintaining headroom. www.maximintegrated.com Maxim Integrated │  9 MAX4238/MAX4239 Ultra-Low Offset/Drift, Low-Noise, Precision SOT23 Amplifiers Ordering Information PART PIN-PACKAGE Selector Guide TOP MARK MAX4238ASA+ 8 SO MAX4238ASA+T 8 SO MAX4238ATT+ 6 TDFN-EP* ANG MAX4238ATT+T 6 TDFN-EP* ANG MAX4238AUT+ 6 SOT23 AAZZ MAX4238AUT+T 6 SOT23 AAZZ MAX4238AUT/V+ 6 SOT23 ACRW MAX4238AUT/V+T 6 SOT23 ACRW MAX4239ASA+ 8 SO MAX4239ASA+T 8 SO MAX4239ATT+ 6 TDFN-EP* MAX4239ATT+T 6 TDFN-EP* ANH MAX4239AUT+ 6 SOT23 ABAA MAX4239AUT+T 6 SOT23 ABAA MAX4239AUT/V+ 6 SOT23 ACRX MAX4239AUT/V+T 6 SOT23 ACRX — — PART MINIMUM STABLE GAIN GAIN BANDWIDTH (MHz) MAX4238 1V/V 1 MAX4239 10V/V 6.5 Chip Information PROCESS: BiCMOS — — ANH Note: All devices are specified over the -40°C to +125°C operating temperature range. +Denotes a lead(Pb)-free/RoHS-compliant package. *EP = Exposed paddle. /V denotes an automotive-qualified part.
