Description :

The LM111, LM211, LM311J-8 and LM311 are voltage comparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710. They are also designed to operate over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5V supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA.

Both the inputs and the outputs of the LM111, LM211 or the LM311 can be isolated from system ground, and the output can drive loads referred to ground, the positive supply or the negative supply. Offset balancing and strobe capability are provided and outputs can be wire OR’ed. Although slower than the LM106 and LM710 (200 ns response time vs 40 ns) the devices are also much less prone to spurious oscillations. The LM111 has the same pin configuration as the LM106 and LM710.


1. Operates from single 5V supply
2. Input current: 150 nA max. over temperature
3. Offset current: 20 nA max. over temperature
4. Differential input voltage range: ±30V
5. Power consumption: 135 mW at ±15V

LTC2620 datasheet


Description :

The LTC2600, LTC2610, LTC2620 are octal 16-, 14- and 12-bit, 2.5V-to-5.5V rail-to-rail voltage-output DACs in 16-lead narrow SSOP and 20-lead 4mm ×5mm QFN packages.

They have built-in high performance output buffers and are guaranteed monotonic.

These parts establish new board-density benchmarks for 16- and 14-bit DACs and advance performance standards for output drive, crosstalk and load regulation in single-supply, voltage-output multiples.

Smallest Pin-Compatible Octal DACs :

LTC2600 : 16 Bits
LTC2610 : 14 Bits
LTC2620 : 12 Bits


  • Wide 2.5V to 5.5V Supply Range
  • Low Power Operation: 250μA per DAC at 3V
  • Individual Channel Power-Down to 1μA, Max
  • Ultralow Crosstalk Between DACs (<10μV)
  • High Rail-to-Rail Output Drive (±15mA, Min)
  • Double-Buffered Digital Inputs
  • Pin Compatible 10-/8-Bit Versions (LTC1660/LTC1665)
  • Tiny 16-Lead Narrow SSOP and 20-Lead 4mm × 5mm QFN Packages

Applications :

1. Mobile Communications

2. Process Control and Industrial Automation

3. Instrumentation

4. Automatic Test Equipment
