Hello all,
i am using OP27 op-amp by analog Devices in my projects, it is working fine but very costly. i requires huge numbers for my project. please can anybody suggest OP27 equivalent Device by TI.
thank you

Suresh,
TI's equivalent to Analog Device's OP27 is the OP27A & OP27C, but TI has a large operational amplifier portfolio, and we may have a better option for your application. Could you provide more information on your requirements and application so that we may find the best suited op amp for your project? And what are your volumes?

Hello sir,
op27 is using precision averaging circuit of gain two, very old product. we need around 15000 op27 per year. it is very costly. please suggest TI's low cast op-amp equivalent to op27. op27 is used in some military communication equipments. so we require mil grade, die form device. if you suggest soon, we can put order very soon for this year.
thank you,

Hi Suresh,
You might want to look at the OPA227 from TI. Below is a brief spec comparison. FYI,
OPA227P/U | OP27A/E | |
Supply Range (V) | +/-18 | +/-22 |
Vos (typ, uV) | 5 | 10 |
Vos Drift (typ, uV/C) | 0.1 | 0.2 |
Input Voltage Noise (typ, nV/rtHz) | 3 @1kHz | 3 @1kHz |
CMRR (min, dB) | 120 | 114 |
Bias Current (typ, nA) | 2.5 | 10 |
GBW (MHz) | 8 | 8 |
Slew Rate (typ, V/us) | 2.3 | 2.8 |
Operating Temp Range (C) | -55 to 125 | -55 t0 125 |
