On-Resistance vs. Capacitance Trade-Off in Multiplexers. (Figure 2. It should be noted that care needs to be practiced in the layout for discrete PGIAs. They do, however, consume more power in comparison to the AD7124-8. Also, because the drains of the multiplexer are shorted together, only a single resistor can be used on one side of the RG  pins, which still leads to imbalances. For the ADG1208, the on-resistance changes by as much as 40 Ω with the source or drain voltage varying from ±15 V. This results in a gain nonlinearity of about 3%. Combined with rail-to-rail input and output, the ISL2853x and ISL2863x instrumentation amplifiers are ideal for single supply low noise, high precision amplification and signal conditioning. The gain is adjustable in 3dB increments across the entire range. Table 1. On-resistance vs. drain voltage for ADG1208.). For larger gains, this error will become even more apparent, and the on-resistance may even start to become comparable to the gain resistor. This device uses proprietary Microchip’s Programmable Gain Amplifiers (PGAs) are not well suited for precision applications (such as CT scanners), but they can be effectively used in position photo sensing applications minus the head-aches of amplifier stability.

In this configuration, the switch is placed in a high impedance sense path, so the gain is not affected by the changing on-resistance of the switch. The AD825x is very useful in multiplexed systems due to its fast settling time and high slew rate. Dual amplifiers should be used for better tracking over temperature. Some of their key features include very high common mode rejection ratio (CMRR), high open loop gain, low DC offset, low drift, low input impedance, and low noise. A bigger problem is that the capacitive imbalance on the RG pins leads to a reduction of ac common-mode rejection ratio (CMRR), which is a key specification of instrumentation amplifiers. The AD625 is a precision instrumentation amplifier specifically designed to fulfill two major areas of application: 1) Circuits re- quiring nonstandard gains (i.e., gains not easily achievable with devices such as the AD524 and AD624). The dynamic range of the LTC6915 is more than 120dB. Data acquisition (DAQ) systems find their use in many industries, for a wide range of applications, such as research, analysis, design verification, manufacturing, and testing. It uses, as the output stage, a current amplifier reported in [11]. By nature, these systems interface to various sensors, which poses a challenge to the front end. For a single-ended output and relatively low bandwidth applications, the AD8276 is a good choice. In this configuration, the on-resistance of the mux is effectively in series with the gain resistor. 2) Circuits requiring a low cost, precision software programmable gain amplifier.

Its gain can be programmed to 10, Supply current over output voltage.). A single external resistor sets the gain from 1 to 1000. For the best gain error and drift performance, a resistor network can be used for its tolerance and temperature coefficient tracking. In order to eliminate the parasitic resistance effects of the switch, an in-amp with a different architecture can be used to implement arbitrary gains. In portable, battery-powered applications, this circuit would be extremely useful and the key specification would not otherwise have been achieved with an integrated PGIA. Table 3 demonstrates this with a comparison of ADG1208 and ADG1408.
