For simplicity, power supply decoupling capacitors are not shown in these diagrams. Non-Inverting Amplifier The OPA836 and OPA2836 can be used as non-inverting amplifiers with signal input to the non-inverting input, VIN+. A basic block diagram of the circuit is shown in Figure 53.

Inverting Amplifier Attenuators The non-inverting circuit of Figure 53 has minimum gain of 1. To implement attenuation, a resistor divider can be placed in series with the positive input, and the amplifier set for gain of 1 by shorting VOUT to VIN- and removing RG. Since the op amp input is high impedance, the attenuation is set by the resistor divider.

The amplifier in essence The signal gain of the circuit is set by: CM combines two non-inverting amplifiers into one differential amplifier with the RG resistor shared, which makes RG effectively ½ its value when calculating the gain. The output signals are in-phase with the input signals.
PAGE 27
OPA836 OPA2836 www.ti.com SLOS712E – JANUARY 2011 – REVISED SEPTEMBER 2013 Integrated solutions are available, but the OPA836 provides a much lower power high frequency solution. For best CMRR performance, resistors must be matched. Assuming CMRR ≈ the resistor tolerance; so 0.1% tolerance will provide about 60 dB CMRR.

OPA836 OPA2836 SLOS712E – JANUARY 2011 – REVISED SEPTEMBER 2013 www.ti.com Input Common-Mode Voltage Range When the primary design goal is a linear amplifier, with high CMRR, it is important to not violate the input common-mode voltage range (VICR) of an op amp. Common-mode input range low and high specifications in the table data use CMRR to set the limit. The limits are chosen to ensure CMRR will not degrade more than 3dB below its limit if the input voltage is kept within the specified range.

This gives excellent distortion performance, maximum bandwidth, best flatness, and best pulse response. It also loads the amplifier.

When driving capacitive loads greater than this, it is recommended to use a small resister (RO) in series with the output as close to the device as possible.

OPA836 OPA2836 SLOS712E – JANUARY 2011 – REVISED SEPTEMBER 2013 www.ti.com Layout Recommendations The OPA836 EVM (SLOU314) should be used as a reference when designing the circuit board. It is recommended to follow the EVM layout of the external components near to the amplifier, ground plane construction, and power routing as closely as possible. General guidelines are: 1. Signal routing should be direct and as short as possible into an out of the op amp. 2.
