The maximum input offset voltage is only 3.5mV and the input common mode range extends beyond the supply rails. TS2177A/TS2178A families of operational amplifiers are specified at the full temperature range of −40C to +125C under single or dual power supplies of 2.7V to 5.5V, however these products will operate under an extended supply range from 2.5V to 5.5V at a reduced temperatures range. The TS2177A and TS2277A have a power-down feature that reduces the supply current to 1μA.

They provide Rail-to-rail input and output. Excellent ac performance makes them wellsuited for audio and sensor applications. The input common-mode voltage range includes both rails, allowing the TS2177A and TS2178A families op amps to be used in bipolar and unipolar application. Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications. Power-supply pins should be bypassed with 0.1F ceramic capacitors. configuration to capacitive loading. Direct capacitive loading reduces the phase margin of amplifiers and this result in ringing or even oscillation. Applications that require greater capacitive driving capability should use an isolation resistor between the output and the capacitive load like the circuit in Figure2. The isolation resistor RISO and the load capacitor CL form a zero to increase stability. The bigger the RISO resistor value, the more stable VOUT will be. Note that this method results in a loss of gain accuracy because RISO forms a voltage divider with the RLOAD. POWER SUPPLY The TS2177A and TS2178A families operate from a single +2.5V to +5.5V supply or dual ±1.25V to ±2.75V supplies. For single supply operation, bypass the power supply +VS with a 0.1μF capacitor which should be placed close to the +VS pin. For dualsupply operation, both the +VS and the -VS supplies should be bypassed to ground with separate 0.1μF ceramic capacitors. 2.2μF tantalum capacitor can be added for better performance. - Riso Vout Vin + CL Figure 2. Indirectly Driving Heavy Capacitive Load An improved circuit is shown in Figure 3. It provides DC accuracy as well as AC stability. Rf provides the DC accuracy by connecting the inverting signal with the output. Cf and RISO serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier’s inverting input, thereby preserving phase margin in the overall feedback loop. The TS2177A and TS2178A families are ideal for battery-powered instrumentation and handheld devices because it can operate at the end of discharge voltage of most popular batteries. +VS 10uF Rf 0.1uF Cf Vin- Vin+ Riso Vout Vin Vout + 0.1uF CL RL 10uF Figure 3. Indirectly Driving Heavy Capacitive Load with DC Accuracy -VS Figure1. Amplifier with Bypass Capacitors For non-buffer configuration, there are two other ways to increase the phase margin: (a) by increasing the amplifier’s gain or (b) by placing a capacitor in parallel with the feedback resistor to counteract the parasitic capacitance associated with inverting node. DRIVING CAPACITIVE LOADS The TS2177A and TS2178A families can directly drive 1000pF in unity-gain without oscillation. The unity-gain follower (buffer) is the most sensitive REV KY1.4.2A 8 www.trusignal.com TS2177A/TS2178A TS2277A/TS2278A TS2478A Trusignal Microelectronics TYPICAL APPLICATIONS Instrumentation Amplifier Differen ce Amplifier R2 R2 R1 Vin1 V- R1 Vout Vin2 VOUT R3 V+ R4 R3 R4 Vref Vref Figure 4. Differential Amplifier Figure 6. Instrumentation Amplifier The circuit shown in Figure 4 performs the difference function. If the resistor ratios are equal (R4 / R3 = R2 / R1) then Vout = (Vin2 – Vin1) × R2 / R1 + Vref. The circuit in Figure 6 performs the same function as that in Figure 4 but with the high input impedance. Low Pass Active Filter C R2 R1 Vout Vin R3 Figure 5. Low Pass Active Filter The low pass filter shown in Figure 5 has a DC gain of (-R2 / R1) and the –3dB corner frequency is 1/2πR2C. Make sure the filter within the bandwidth of the amplifier. The Large values of feedback resistors can couple with parasitic capacitance and cause undesired effects such as ringing or oscillation in high-speed amplifiers. Keep resistors value as low as possible and consistent with output loading consideration.
