Reviews Picoamp Input Bias Current

Texas Instruments INA126PA Single SP Instrumented Amplifier, 18-36 V, 8-Pin, 9.81 mm L x 6.35 mm W x 4.57 mm H (Pack of 2), 6.35 millimeters Width, 9.81 millimeters Length, Volts (Pack of 2)

...dge type without compromise. Signal switching is performed at high level and low impedance (via relays) ensuring there is no degradation of the signal..
The MC input uses parallel connected, low noise FET's (Field Effect Transistor's) configured as a compound pair. The use of FET transistors ensures there is no bias current flowing in the cartridge coil so as not to upset the delicate magnetic geometry of the cartridge. The MC input has the provision for selecting resistive input loading of 70ohms to 400ohms and capacitive loading of 1000pF to 4200pF. The input sensitivity can be changed by 6dB via the back panel..
The MM input uses low noise, bipolar input transistors also configured as a compound pair. There are two separate power supplies for each channel and further sub-power supplies for each of the low noise input circuits. Nichicon FG electrolytic capacitors have been used in critical positions throughout the power supplies. Polypropylene capacitors have been used in the signal path and equalization networks..

1.The MAX9814 is a high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone-bias-voltage generator and AGC control circuitry..
2.A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor programs the attack/release times..
3.The low-noise preamplifier has a fixed 12dB gain, while the VGA gain automatically adjusts from 20dB to 0dB, depending on the output voltage and the AGC threshold. The output amplifier offers selectable gains of 8dB, 18dB, and 28dB. With no compression, the cascade of the amplifiers results in an overall gain of 40dB, 50dB, or 60dB..
4.The MAX9814 is available in the space-saving, 14-pin TDFN package. This device is specified over the -40°C to +85°C extended temperature range. MAX9814: Simplified Block Diagram MAX9814: Simplified Block Diagram Enlarge+.
5.A trilevel digital input programs the ratio of attack-to-release time. The hold time of the AGC is fixed at 30ms. The low-noise microphone-bias-voltage generator can bias most electret microphones..
