LT6202/LT6203/LT6204 Single/Dual/Quad 100MHz, Rail-to-Rail Input and Output, Ultralow 1.9nV/√Hz Noise, Low Power Op Amps FEATURES DESCRIPTION n n n n n n n n n n n n n n n Low Noise Voltage: 1.9nV/√Hz (100kHz) Low Supply Current: 3mA/Amp Max Gain Bandwidth Product: 100MHz Dual LT6203 in Tiny DFN Package Low Distortion: –80dB at 1MHz Low Offset Voltage: 500µV Max Wide Supply Range: 2.5V to 12.6V Input Common Mode Range Includes Both Rails Output Swings Rail-to-Rail Common Mode Rejection Ratio 90dB Typ Unity Gain Stable Low Noise Current: 1.1pA/√Hz Output Current: 30mA Min Operating Temperature Range –40°C to 125°C Low Profile (1mm) SOT-23 (ThinSOT ™) Package The LT®6202/LT6203/LT6204 are single/dual/quad low noise, rail-to-rail input and output unity gain stable op amps that feature 1.9nV/√Hz noise voltage and draw only 2.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 100MHz gain bandwidth product, a 25V/µs slew rate, and are optimized for low supply signal conditioning systems. These amplifiers maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. Harmonic distortion is less than – 80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems. The LT6202 is available in the 5-pin TSOT-23 and the 8-pin SO, while the LT6203 comes in 8-pin SO and MSOP packages with standard op amp pinouts. For compact layouts the LT6203 is also available in a tiny fine line leadless package (DFN), while the quad LT6204 is available in the 16-pin SSOP and 14-pin SO packages. These devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Inputs are protected by back-to-back diodes and diodes to each supply. If the inputs are taken beyond the supplies or the differential input voltage exceeds 0.7V, the input current must be limited to less than 40mA. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The LT6202C/LT6203C/LT6204C are guaranteed to meet specified performance from 0°C to 70°C. The LT6202C/LT6203C/LT6204C are designed, characterized and expected to meet specified performance from –40°C to 85°C, but are not tested or QA sampled at these temperatures. The LT6202I/LT6203I/LT6204I are guaranteed to meet specified performance from –40°C to 85°C. The LT6202H and LT6203H are guaranteed to meet specified performance from –40°C to 125°C. MIN UNITS mA MHz Note 5: Matching parameters are the difference between the two amplifiers A and D and between B and C of the LT6204; between the two amplifiers of the LT6203. CMRR and PSRR match are defined as follows: CMRR and PSRR are measured in µV/V on the identical amplifiers. The difference is calculated between the matching sides in µV/V. The result is converted to dB. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested. Note 9: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πVP Note 10: Differential gain and phase are measured using a Tektronix TSG120YC/NTSC signal generator and a Tektronix 1780R Video Measurement Set. The resolution of this equipment is 0.1% and 0.1°. Ten identical amplifier stages were cascaded giving an effective resolution of 0.01% and 0.01°. 620234fd 12 LT6202/LT6203/LT6204 TYPICAL PERFORMANCE CHARACTERISTICS VOS Distribution, VCM = V+/2 45 60

LT6202/LT6203/LT6204 APPLICATIONS INFORMATION Amplifier Characteristics Figure 1 shows a simplified schematic of the LT6202/ LT6203/LT6204, which has two input differential amplifiers in parallel that are biased on simultaneously when the common mode voltage is at least 1.5V from either rail. This topology allows the input stage to swing from the positive supply voltage to the negative supply voltage. As the common mode voltage swings beyond VCC – 1.5V, current source I1 saturates and current in Q1/Q4 is zero. Feedback is maintained through the Q2/Q3 differential amplifier, but with an input gm reduction of 1/2. A similar effect occurs with I2 when the common mode voltage swings within 1.5V of the negative rail. The effect of the gm reduction is a shift in the VOS as I1 or I2 saturate. R1 –V The second stage is a folded cascode and current mirror that converts the input stage differential signals to a single ended output. Capacitor C1 reduces the unity cross frequency and improves the frequency stability without degrading the gain bandwidth of the amplifier. The differential drive generator supplies current to the output transistors that swing from rail-to-rail. + R2 I1 – +V DESD1 Input bias current normally flows out of the + and – inputs. The magnitude of this current increases when the input common mode voltage is within 1.5V of the negative rail, and only Q1/Q4 are active. The polarity of this current reverses when the input common mode voltage is within 1.5V of the positive rail and only Q2/Q3 are active.

Simplified Schematic 620234fd 18 LT6202/LT6203/LT6204 APPLICATIONS INFORMATION Input Protection There are back-to-back diodes, D1 and D2, across the + and – inputs of these amplifiers to limit the differential input voltage to ±0.7V. The inputs of the LT6202/LT6203/ LT6304 do not have internal resistors in series with the input transistors. This technique is often used to protect the input devices from over voltage that causes excessive currents to flow. The addition of these resistors would significantly degrade the low noise voltage of these amplifiers. For instance, a 100Ω resistor in series with each input would generate 1.8nV/√Hz of noise, and the total amplifier noise voltage would rise from 1.9nV/√Hz to 2.6nV/√Hz. Once the input differential voltage exceeds ±0.7V, steady state current conducted though the protection diodes should be limited to ±40mA. This implies 25Ω of protection resistance per volt of continuous overdrive beyond ±0.7V. The input diodes are rugged enough to handle transient currents due to amplifier slew rate overdrive or momentary clipping without these resistors. Figure 2 shows the input and output waveforms of the amplifier driven into clipping while connected in a gain of AV = 1. When the input signal goes sufficiently beyond the power supply rails, the input transistors will saturate. When saturation occurs, the amplifier loses a stage of phase inversion and the output tries to change states. Diodes D1 and D2 forward bias and hold the output within a diode drop of the input signal. In this photo, the input signal generator is clipping at ±35mA, and the output transistors supply this generator current through the protection diodes. With the amplifier connected in a gain of AV ≥ 2, the output can invert with very heavy input overdrive. To avoid this inversion, limit the input overdrive to 0.5V beyond the power supply rails. ESD The LT6202/LT6203/LT6204 have reverse-biased ESD protection diodes on all inputs and outputs as shown in Figure 1. If these pins are forced beyond either supply, unlimited current will flow through these diodes. If the current is transient and limited to one hundred milliamps or less, no damage to the device will occur. Noise The noise voltage of the LT6202/LT6203/LT6204 is equiva lent to that of a 225Ω resistor, and for the lowest possible noise it is desirable to keep the source and feedback resistance at or below this value, i.e. RS + RG||RFB ≤ 225Ω. With RS + RG||RFB = 225Ω the total noise of the amplifier is: en = √(1.9nV)2+(1.9nV)2 = 2.7nV. Below this resis tance value, the amplifier dominates the noise, but in the resistance region between 225Ω and approximately 10kΩ, the noise is dominated by the resistor thermal noise. As the total resistance is further increased, beyond 10k, the noise current multiplied by the total resistance eventually dominates the noise. The product of en • √ISUPPLY is an interesting way to gauge low noise amplifiers. Many low noise amplifiers with low en have high ISUPPLY current. In applications that require low noise with the lowest possible supply current, this product can prove to be enlightening. The LT6202/LT6203/LT6204 have an en, √ISUPPLY product of 3.2 per amplifier, yet it is common to see amplifiers with similar noise specifications have an en • √ISUPPLY product of 4.7 to 13.5. OV Figure 2.

The LT6202 forces the BF862 ultralow-noise JFET source to 0V, with R3 ensuring that the JFET has an IDRAIN of 1mA. The JFET acts as a source follower, buffering the input of the LT6202 and making it suitable for the high impedance feedback elements R1 and R2. The BF862 has a minimum IDSS of 10mA and a pinchoff voltage between –0.3V and –1.2V. The JFET gate and the LT6202 output VS+ R1 499k R2 499k – C1 1pF PHILIPS BF862 VBIAS– + therefore sit at a point slightly higher than one pinchoff voltage below ground (typically about –0.6V). When the photodiode is illuminated, the current must come from the LT6202’s output through R1 and R2, as in a normal TIA. Amplifier input noise density and gain-bandwidth product were measured at 2.4nV/Hz and 100MHz, respectively. Note that because the JFET has a high gm, approximately 1/80Ω, its attenuation looking into R3 is only about 2%. Gain-bandwidth product was measured at 100MHz and the closed-loop bandwidth using a 3pF photodiode was approximately 1.4MHz. Precision Low Noise, Low Power, 1MΩ Photodiode Transimpedance Amplifier LT6202 Figure 4 shows the LT6202 applied as a transimpedance amplifier (TIA), very similar to that shown in Figure 3. In this case, however, the JFET is not allowed to dictate the DC-bias conditions. Rather than being grounded, the LT6202’s noninverting input is driven by the LTC2050 to the exact state necessary for zero JFET gate voltage. The noise performance is nearly identical to that of the circuit in Figure 3, with the additional benefit of excellent DC performance. Input offset was measured at under 200µV and output noise was within 2mVP-P over a 20MHz bandwidth. VOUT R3 4.99k VS = ±5V – LT6202/03/04 F03 VS Figure 3.

The bottom half of the LT6203 is in a gain-of-one configuration and buffers the 0V negative full-scale signal VLOW into the negative input of the LTC1864. The top half of the LT6203 is in a gain-of-ten configuration referenced to the buffered voltage VLOW and drives the positive input of the LTC1864. The input range of the LTC1864 is 0V to 5V, but for best results the input range of VIN should be from VLOW (about 0.4V) to about 0.82V. Figure 6 shows an FFT obtained with a 10.1318kHz coherent input waveform, from 8192 samples with no windowing or averaging. Spurious free dynamic range is seen to be about 100dB. 5V R3 100Ω + VIN = 0.6VDC ±200mVAC Although the LTC1864 has a sample rate far below the gain bandwidth of the LT6203, using this amplifier is not necessarily a case of overkill. The designer is reminded that A/D converters have sample apertures that are vanishingly small (ideally, infinitesimally small) and make demands on the upstream circuitry far in excess of what is implied by the innocent-looking sample rate. In addition, when an A/D converter takes a sample, it applies a small capacitor to its inputs with a fair amount of glitch energy and expects the voltage on the capacitor to settle to the true value very quickly. Finally, the LTC1864 has a 20MHz analog input bandwidth and can be used in undersampling applications, again requiring a source bandwidth higher than Nyquist. 1/2 LT6203 – R1 1k + C1 470pF R2 110Ω + R4 100Ω – SERIAL DATA OUT 1/2 LT6203 – LT6202/03/04 F05 Figure 5.
