The 2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The LM4040 uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-toperformance ratio for their applications. 1 • • • • • Fixed Output Voltages of 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V Tight Output Tolerances and Low Temperature Coefficient – Max 0.1%, 100 ppm/°C – A Grade – Max 0.2%, 100 ppm/°C – B Grade – Max 0.5%, 100 ppm/°C – C Grade – Max 1.0%, 150 ppm/°C – D Grade Low Output Noise: 35 μVRMS Typ Wide Operating Current Range: 45 μA Typ to 15 mA Stable With All Capacitive Loads; No Output Capacitor Required Available in Extended Temperature Range: –40°C to 125°C 2 Applications • • • • • • • • Data-Acquisition Systems Power Supplies and Power-Supply Monitors Instrumentation and Test Equipment Process Controls Precision Audio Automotive Electronics Energy Management Battery-Powered Equipment Packaged in space-saving SC-70 and SOT-23-3 packages and requiring a minimum current of 45 μA (typ), the LM4040 also is ideal for portable applications. The LM4040xI is characterized for operation over an ambient temperature range of –40°C to 85°C. The LM4040xQ is characterized for operation over an ambient temperature range of –40°C to 125°C.

The LM4040 has been designed for stable operation without the need of an external capacitor connected between the “+” pin and the “−” pin. If, however, a bypass capacitor is used, the LM4040 remains stable. LM4040 offers several fixed reverse breakdown voltages: 2.048 V, 2.500 V, 3.000 V, 4.096 V, 5.000 V, 6.000, 8.192 V, and 10.000 V. The minimum operating current increases from 60 µA for the LM4040-N-2.048 and LM4040-N-2.5 to 100 μA for the 10.0-V LM4040. All versions have a maximum operating current of 15 mA. Each reverse voltage options can be purchased with initial tolerances (at 25°C) of 0.1%, 0.2%, 0.5% and 1.0%. These reference options are denoted by A (0.1%), B (0.2%), C (0.5%) and D for (1.0%). The LM4040xxxI devices are characterized for operation from –40°C to 85°C, and the LM4040xxxQ devices are characterized for operation from –40°C to 125°C. 7.2 Functional Block Diagram CATHODE + _ ANODE 7.3 Feature Description A temperature compensated band gap voltage reference controls high gain amplifier and shunt pass element to maintain a nearly constant voltage between cathode and anode. Regulation occurs after a minimum current is provided to power the voltage divider and amplifier. Internal frequency compensation provides a stable loop for all capacitor loads. Floating shunt design is useful for both positive and negative regulation applications. 7.4 Device Functional Modes 7.4.1 Shunt Reference LM4040 will operate in one mode, which is as a fixed voltage reference that cannot be adjusted. LM4040 does offer various Reverse Voltage options that have unique electrical characteristics detailed in the Specifications section. In order for a proper Reverse Voltage to be developed, current must be sourced into the cathode of LM4040. The minimum current needed for proper regulation is denoted in the Specifications section as IZ,min.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information LM4040 is a well known industry standard device used in several applications and end equipment where a reference is required. Below describes this device being used in a data acquisition system. Analog to Digital conversion systems are the most common applications to use LM4040 due to its low reference tolerance which allows high precision in these systems. 8.2 Typical Applications ADS7842 0 V to VREF 1 AIN0 5V 2 AIN1 909 + 2.2 mF LM4040A-41 VANA VDIG 28 + 27 3 AIN2 A1 26 4 AIN3 A0 25 5 VREF CLK 24 5-V Analog Supply + 0.1 mF 10 mF 3.2-MHz Clock BUSY 23 BUSY Output 7 DB11 WR 22 Write Input 8 DB10 CS 21 9 DB9 RD 20 6 AGND 10 DB8 DB0 19 11 DB7 DB1 18 12 DB6 DB2 17 13 DB5 DB3 16 14 DGND DB4 15 Read Input Figure 6.

LSB can be determined by: LSB=FSR/(2N-1) With N being the resolution or Number of Bits. FSR and Resolution can be determined by the ADC's datasheet. Vref can be determined by: Vref=FSR+LSB Though modern data converters use calibration techniques to compensate for any error introduced by a Vref's inaccuracy, it is best to use the highest accuracy available. This is due to errors in the calibration method that may allow some non-linearities introduced by the Vref's initial accuracy. A good example is the LM4040x-41 that is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition systems. For 12-bit systems operating from 5-V supplies (see Figure 6), the LM4040A-41 (4.096 V, 0.01%) only introduces 4 LSBs (4mV) of possible error in a system that consists of 4096 LSBs. 8.2.2.2 Cathode and Load Currents In a typical shunt-regulator configuration (see Figure 7), an external resistor, RS, is connected between the supply and the cathode of the LM4040. RS must be set properly, as it sets the total current available to supply the load (IL) and bias the LM4040 (IZ). In all cases, IZ must stay within a specified range for proper operation of the reference. Taking into consideration one extreme in the variation of the load and supply voltage (maximum IL and minimum VS), RS must be small enough to supply the minimum IZ required for operation of the regulator, as given by data-sheet parameters. At the other extreme, maximum VS and minimum IL, RS must be large enough to limit IZ to less than its maximum-rated value of 15 mA. RS is calculated according to Equation 1: (V - VZ ) RS = S (IL + IZ ) (1) VS RS IZ + IL IL VZ IZ LM4040 Figure 7. Shunt Regulator 8.2.2.3 Output Capacitor The LM4040 does not require an output capacitor across cathode and anode for stability. However, if an output bypass capacitor is desired, the LM4040 is designed to be stable with all capacitive loads.

Thus, pin 3 of the SOT-23 package must be left floating or connected to pin 2. 8.2.2.5 Start-Up Characteristics In any data conversion system, start-up characteristics are important, as to determine when it is safe begin conversion based upon a steady and settled reference value. As shown in Figure 9 it is best to allow for >20µs from supply start-up to begin conversion. RS VIN LM4040 VZ 1 Hz Rate Figure 8.

For applications shunting high currents (15 mA max), pay attention to the cathode and anode trace lengths, adjusting the width of the traces to have the proper current density. 10 Layout 10.1 Layout Guidelines Figure 10 shows an example of a PCB layout of LM4040XXXDBZ. Some key Vref noise considerations are: • Connect a low-ESR, 0.1-μF (CL) ceramic bypass capacitor on the cathode pin node. • Decouple other active devices in the system per the device specifications. • Using a solid ground plane helps distribute heat and reduces electromagnetic interference (EMI) noise pickup. • Place the external components as close to the device as possible. This configuration prevents parasitic errors (such as the Seebeck effect) from occurring. • Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if possible and only make perpendicular crossings when absolutely necessary. 10.2 Layout Example GND DBZ (TOP VIEW) CL Rsup Vsup CATHODE GND ANODE 1 3 2 Figure 10.
