  • OPA861: OPA861 in LDO application

    TI Thinks Resolved
    Part Number: OPA861 Hi team, I am trying to use the OPA861 in an application to create a discrete, unity gain LDO. When I run the simulations in PSpice, I get expected behavior; however, this circuit is not acting like an LDO in the real world, when…

  • RE: OPA1S2384: op-amp selection

    Hello Hale, Please find my comparison below: sample_and_hold_comparison.xlsx The key differences between OPA1S2384/5 and OPA860/1 are here: - OPA860/1 are OTA, or operational transconductance amplifiers. They are primarily intended for laser drivers and…

  • OPA861 -- math mistake in LPF

    Other Parts Discussed in Thread: OPA861 The datasheet for the OPA861 appears to have a math mistake in the calculation of component values for the low pass filter. If frequency is 20kHz, and R is 1k, C2=0.008uF and C1=0.004uF. The values for the 10MHz…

  • OPA860: best for generating a low amplitude (1 mA) sinusoidal current between 50 - 100 kHz.

    TI Thinks Resolved
    Part Number: OPA860 Other Parts Discussed in Thread: OPA861 , OPA615 , LM13700 , OPA2210 Hi Team, The customer is working on a voltage-controlled current source and would like to use an operational transconductance amplifier (OTA) integrated circuit and they…

  • pcm1794 and opa861 based i/v stage

    Other Parts Discussed in Thread: PCM1794 , OPA861 Dear I have a dac with pcm1794 and the output stage is the same of datasheet. I'm happy for this but i'm looking for another configuration that use no feedback IC. i assume a pattern like: DAC out -…

  • Quiescent current

    Other Parts Discussed in Thread: OPA861 , TLE2426 Hello, I'm a little bit confused about the quiescent current of the OPA861. Im my application, I'm using the OPA861 in a single supply configuration with 6.6V DC. I'm also using a TLE2426 as a Vbias…

  • RE: Best transimpedance multiplexing technique with OPA842/OPA847 (highly dynamic TIA)

    Hello Samir, Something like : Bias(150V)->Photodiode (Cd=15pF) -> Resistance of 50Ohm between photodiode_anode and GND. A OPA861 connected to the photodiode_anode and a R1/R2 on the OPA861 to be able to lower the current. R1/R2 is configurable. …
