Frequently Asked Questions
What is the input bias current specification for TLV9042IDGKR and why does it matter for precision circuits?
The TLV9042IDGKR has a maximum input bias current of 12 pA at 25°C, which is extremely low. This allows it to interface with high-impedance sources such as pH sensors or photodiodes without introducing significant voltage error from bias current flowing through source resistance.
Which supply voltage range does TLV9042IDGKR support for single-supply portable designs?
The TLV9042IDGKR operates from a single supply of 1.8 V to 5.5 V, making it suitable for 3.3 V and 5 V systems. This wide range supports portable and battery-powered equipment where supply rails may vary, and the rail-to-rail output maximizes usable dynamic range.
How many op-amp channels does TLV9042IDGKR provide, and what package does it use?
TLV9042IDGKR contains 2 independent op-amp channels in an 8-pin MSOP (VSSOP) package with a 3 mm × 3 mm footprint. The dual configuration reduces board space compared to two single-channel devices while keeping pin count to 8 pins.
When is TLV9042IDGKR a suitable alternative to the TLV9002 in a design?
TLV9042IDGKR offers a higher CMRR of 89 dB typical versus the TLV9002's lower-spec variants, making it preferable when common-mode noise rejection is critical in differential measurement paths. Both share the same 1.8 V to 5.5 V supply range and 8-pin footprint, easing migration. Choose TLV9042IDGKR when the 12 pA bias current specification is needed.
